Subject: [libxml-devel] xpath searching without specifying namespace?
Message-ID: <5C597C9B5C994108BBE1F4F1E4F1ACEB@windows.esseff.org>

I'm stumbled across this in my own work.

mortee says:

	The docs for XML::XPath.find suggest that if I omit the namespace
	specification, then "matching nodes from any namespace will be
included".

and it doesn't.

I'd argue this is a doc error.

Even if one thought this was a good idea, matching any namespace, under the
rubric "make simple things easy", I don't think you're ever going to get
libxml to do it. Proper namespace handling is too ingrained.

I stumbled upon code that tried to hack the xpath expression to handle
default namespaces. Creepy code.

There's really no safe solution since the same prefix can mean different
things at different points in a doc.

The "best" solution is probably to remove the namespace from the root
element (and the doctype, if necessary, I guess). But that won't match all
default namespaces: you can always write

<a xmlns="http://a">
  <b xmlns="http://b">
    <a/>
  </b>
</a>

and removing the top level ns isn't going to make //a match both <a> nodes.

If you really want to do that, you probably need to parse the doc, walk it,
writing out nodes w/o the namespace, and then reparse it.

I have done as was suggested: I've read the posts & there are similar  
messages but unfortunately not ones I can understand or use. So with  
apologies for my stupidity, please could you suggest ways to get

ruby -v  gives: ruby 1.8.6 (2007-03-13 patchlevel 0) [universal-

Message-ID: <9c488907-2d44-4f2a-bcd4-d64c93d21575@s12g2000prg.googlegroups.com>

I'm following through the w3schools tutorial on xsd and xml validation
and I'm trying to get one of the examples to validate. The problem
seems to be in validating the attributes because if I strip them out,
then it validates fine. I'm blindly following the tutorial but I can't
see anything wrong with the xsd file, so dare I question if there is a
bug?

Stripping out the w3schools example somewhat, if I was to take the
following schema:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<!-- definition of attributes -->
<xs:attribute name="orderid" type="xs:string"/>

<xs:element name="shiporder">
 <xs:complexType>
  <xs:attribute ref="orderid" use="required"/>
 </xs:complexType>
</xs:element>

</xs:schema>


An xml file:

<?xml version="1.0" encoding="ISO-8859-1"?>

<shiporder orderid="889923" xmlns:xsi="http://www.w3.org/2001/
XMLSchema-instance" xsi:noNamespaceSchemaLocation="validator.xsd">

</shiporder>

and a test script:

require 'xml/libxml'
include XML

xsd_string = ""

File.open('validator.xsd', 'r') do |f1|
  while line = f1.gets
    xsd_string += line
  end
end

doc = Document.file('test.xml')

schema = XML::Schema.from_string( xsd_string )

print doc.validate(schema)


Then I get the following errors

>ruby test.rb
false
error -- found validity error: No declaration for attribute orderid of
element shiporder
error -- found validity error: No declaration for attribute
noNamespaceSchemaLocation of element shiporder
error -- found validity error: No declaration for attribute xmlns:xsi
of element shiporder

I would have thought that the attribute declaration of orderid would
avoid the first error, and that the other two attributes wouldn't need
to be declared.

If the examples are really unclear, the complete xml and xsd is
available at http://www.w3schools.com/schema/schema_example.asp

Cheers

Please verify your validation results using the libxml2 included  
binaries, in this case 'xmllint'. There has been no recent work on the  
validation pass through, which is the same as saying I do not know if  
the ruby library has any culpability. Thus, try the xmlsoft tools. http://xmlsoft.org/xmllint.html

Hi Glenn,

I've just been trying to figure out why I couldn't get XSD validation
to work at all, never mind if I stripped out the attributes, and I
just spotted a validate_schema method of XML::Document that made
validation instantly work for me.

So the code you have above would look something like this:

    ...
    document = XML::Document.file("test.xml")
    schema = XML::Schema.from_string(xsd_string)
    ...

document.validate_schema(schema)     # should return true if your doc
matches your schema

Incidentally I couldn't find this method mentioned in the rdocs
anywhere I only saw it by spotting it in the list of methods of
XML::Document. For example in an irb session:

document = XML::Document.new
document.methods.sort                # prints out all methods that
document responds to

Yes, you're right. validate_schema is listed as a method of
XML::Document but never appears in the method description. Unless
there is a ruby syntax quirk I'm not aware of.

I did see the validate_schema method in the top right hand methods
list, but it says validate_schema(XML::Document), rather than
validate_schema(XML::Schema) which confused me somewhat.

Unfortunately I've just found out that xmllint doesn't insert missing
default values. Well, at least I can validate now.

Thanks

My last experience with ruby and valgrind was kinda unpleasant.  Maybe
with ruby 1.9 it will be better but I don't really have the stomach for
changing my entire test environment right now.

Worst still, as soon as I had packed up a tar file of the code that lead
to the crash, it stopped crashing.  :-(

Maybe I'll get something more reproducible later.  I'll post more
stacktraces, etc as I get them unless the list maintainers would rather
I didn't.

Marc,

I have yet to have valgrind produce anything meaningful in debugging  
this environment. I have tried the suppressions, but alas, nothing. If  
someone can offer an effective way of using it, I am quite interested.

As for this bug, the context code is pretty simple. This is different  
than double-free, so it may be that the memory is being stomped on by  
something else.

I have no insight. Please post what you can to get to the bottom of it.

Dan

The best debugging mechanism that I've found to date is to do  
something along these lines (works in GC'ed environments or not, and  
with setjmp(3) and longjmp(3)).  It doesn't solve the memory stomping  
bits, but it does solve the what's leaking.  If you change my_malloc()  
to a more general macro (eg: MALLOC()) and recode to the new macro,  
you can get more useful info using __FUNCTION__ and __LINE__ to figure  
out where.

FILE *memory_debug_io = fopen("memdump.txt", "w+");

#define MALLOC(ret, size) do { \
   if (memory_debug_io == NULL) \
     memory_debug_io = fopen("memdump.txt", "w+"); \
   ret = malloc(s); \
   fprintf(memory_debug_io, "%s:%u: Allocated %llu bytes at region %x 
\n", __FUNCTION__, __LINE__, (uint64_t)size, ret); \
} while (0)


I use derivations of MALLOC() all the time and find it to be much more  
useful than most of the other utilities because it can incorporate  
information only easily found at compile time.  Putting together a  
script that refcounts addresses found in memdump.txt is pretty easy  
and solves a ton of the tedium of having to look for un-free(3)'ed  
bullshat.

While I can't fully endorse the practice yet as I'm still testing it  
out as a means of development right now, but...  The concept being,  
allocate haphazardly (fight the urge to be hyper meticulous), and  
reconcile free(3)'ing memory later during regression testing.  So far  
it's saved me a ton of time and I'm at roughly 20K LOC of C.  Food for  
thought regarding the valgrind discussion.  -sc

Subject: [libxml-devel] extconf failure: need libm - installing libxml on
	Fedora Core 6
Message-ID: <223020e60801120922l796d0cd5h3e1f6648cc0ac689@mail.gmail.com>

Hello,

I'm trying to build libxml-ruby on Fedora Core 6, but get the following errors:

 bash-3.1# ruby extconf.rb --with-zlib-dir=/usr/lib64/
--with-zlib-include=/usr/include/bzlib.h --with-mlib=/lib/libm.so.6
checking for socket() in -lsocket... no
checking for gethostbyname() in -lnsl... no
checking for atan() in -l/lib/libm.so.6... no
checking for atan() in -l/lib/libm.so.6... no
 extconf failure: need libm
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.


I've tried with all the different libm directories I can find using #
locate libm (/lib /lib64 /usr/lib /usr/lib64)- but I keep getting this
error.  I guess this is a problem with some compiler flags, but don't
really know where to start.

Thanks in advance for the help.

I believe the options to extconf.rb. Expect a directory not an exact
file... Hope this helps

Make sure you've got the glibc-devel package installed - that should
be all you need to build against libm on Fedora.

Thanks for the replies.

Tom: I have glibc-devel version 2.5 installed already.

Todd: I have also tried passing a directory to extconf (
--with-mlib=/lib/) but still no luck.

Looking at the output, that is wrong - it is passing what give there
to the compiler as an argument to -l and it is wrong to give a full
path there. You just want --with-mlib=m I think but that should be
the default anyway I would imagine.

What happens if you don't give a --with-mlib switch?

I think you need to post your mkmf.log file. I just tried it on
an FC6 box and it works for me.

I've posted mkmf.log here:

http://www.blacksworld.net/fedora/mkmf.log

-L"/usr/lib64" is part of the gcc command and the directory has a sym
link to libm:

# ls -l /usr/lib64/libm*
-rw-r--r-- 1 root root 1320734 Jul  4  2007 /usr/lib64/libm.a
lrwxrwxrwx 1 root root      21 Jan 12 13:24 /usr/lib64/libm.so ->
../../lib64/libm.so.6

The "have_library: checking for atan() in -l/lib64...
-------------------- no" message  also seems strange.

Cheers,

That log is from a --with-mlib=/lib64 run, which is bogus, as
evidenced by the "ld: cannot find -l/lib64" error. Try it withou
the --with-mlib switch and post the mkmf.log for that.

Ok - mkmf.log for:

# ruby extconf.rb --with-zlib-include=/usr/include/bzlib.h

is here: http://www.blacksworld.net/fedora/mkmf.log

This does give "cc1: error: /usr/include/bzlib.h: not a directory"
errors, so I also ran:

# ruby extconf.rb

and posted mkmf.log here: http://www.blacksworld.net/fedora/mkmf.log.no_options

Aha! The problem is your --with-zlib-include=/usr/include/bzlib.h switch
which is breaking all the calls to CC including the ones which don't
actually want zlib.

That should be --with-zlib-include=/usr/include but probably isn't
really needed at all as that is the default place for it to look.

All --xxx-include and --xxx-lib switches should name the directory
containing the file(s), not the file itself.

Ok - thanks for the tip.

 extconf still isn't successfully running though - its failing to find
libz, so far as I can see gcc is looking for it in /usr/lib64 and for
the headers in /usr/include, which have the headers and the library.

mkmf.log from # ruby extconf.rb  is here

Do you have /usr/lib64/libz.so? It looks like you don't, but that
would imply you don't have the zlib-devel package installed but if
that is the case I don't understand why you have the header files?

bingo - I created a sym link doing this:

# ls -l /usr/lib64/libz.*
-rwxr-xr-x 1 root root 108692 Jul 19  2006 /usr/lib64/libz.a
lrwxrwxrwx 1 root root     13 Jan 13 18:46 /usr/lib64/libz.so -> libz.so.1.2.3
...
...

and the install worked.  Previously I had libz.so.1 and libz.so.1.2.3,
which seems to have been the cause of the problem.

Thanks for the help Tom.

Subject: [libxml-devel] More wierdness
Message-ID: <1200355010.17286.18.camel@bloodnok.com>

It's beginning to look as though something in one of my xml documents
has been removed part-way through my use of it.

I am trying to discover exactly what is happening but I have a question
about how ruby and C objects interact within libxml.

My understanding is that a mapping is maintained between the C objects
and the ruby objects, and any pointer problems should be due to this map
being in some way incorrect, or incomplete.

Given that I am using both the xml and xsl libraries, and am using
significant numbers of xpath expressions, is it possible that an xml
object (object1) from the xsl library becomes known to the ruby xml
library mappings through an xpath expression?  In this case, wouldn't
the mapping within libxml show that the object has no references and can
therefore be freed, even though there are references from the xsl side
of things?

To put it another way, is there any integration of the mapping mechanism
between libxml and libxsl, and if not should there be?

I'm also having difficulties with this issue, and while I feel that
libxml could be perfect for what I need, the fact that the
documentation seems both very minimal, and a bit out of date is making
me wonder whether I'll be able to use it for the app I'm working on.

To reprise my situation:

* searching for elements using XPath in a document with no namespace
declaration works fine
* searching for elements using XPath in a document that has defined a
prefixed namespace declaration also works fine, provided the XPath
query specifies the prefix as well as the desired element names
* however I can't get _any_ search results when looking for elements
in a document that has specified a namespace, but with the default/
empty prefix.

Am I doing something stupid; or is this something that has been
addressed in the latest head in subversion? If so is there any info on
how to build the library from subversion? I did a quick checkout to
have a look, and it looks like some additional hoops need to be jumped
through before being able to build and install the latest head.

Thanks for any information.

	* however I can't get _any_ search results when looking for elements
	in a document that has specified a namespace, but with the default/
	empty prefix.

You have to make whatever default namespaces you use explicit, e.g., try
something like this example for xhtml:

    items = doc.find '//x:span', "x:http://www.w3.org/1999/xhtml"

The original poster said that //* wasn't returning anything, which I can't
duplicate: it returns everything for me, which I believe is the correct
behavior.

Hey Steven,

wow thanks, that works exactly as advertised!

Incidentally, was this just something you figured out through experiment or
is it documented somewhere and I missed it?

thanks again

I ended up looking at the code. I think, after I figured it out, I was able
to interpret the documentation correctly, but I didn't find it obvious at
first. And googling returns some bad examples, which didn't help.

The basics are there. The XSLT extension tracks the ruby document peer  
that it is working against. The XSLT mark() marks the document peer,  
which should retain the reference. XPath returns node sets and those  
nodes reference their parent doucment, so when the GC runs, the  
Document is marked and should be preserved. The only instance where  
the document relationship is broken is when a clone() occurs. This is  
the intended operation.

If you have a node with no document reference, then it is a copied  
subtree. What ruby object/reference do you have that is missing the  
document?

Doh!
My mistake, never mind.  I had extracted the missing node myself in an
earlier operation.  I'm still experiencing odd crashes, usually when my
app causes an exception in a test unit but nothing I have yet been able
to track down or reliably reproduce.

Sorry for the interruption.  More info when I get it.

Please send me a documentation paragraph that I can add to .find which

eliminate future confusion over the usage.

	Please send me a documentation paragraph that I can add to .find
which  
	makes this more explicit and understandable. Hopefully this will  
	eliminate future confusion over the usage.

There is a little bit of documentation, but it's in the XPath class, which
takes a little tracking down. It doesn't help the the XPath rdocs are messed
up: the doc for .find ends up in XML::XPath::InvalidPath for reasons I
haven't been able to ferret out.

Here's a patch that tries to explain things, as applied to the XPath file.
(I haven't looked too hard into why this is getting put in the wrong place,
though I guess I could.) This could be moved in whole to the Node class if
desired or a pointer from the Node class to the XPath class.

Am I the only one, or is the trunk kinda broken? ext/xml got moved to
ext/libxml last month with, it seems like, the results that everything
broke, e.g., rake test.

I have a patch so I could sanity check this but since it's been sitting
broken for so long and there are some subtleties to binary extensions that
I'm not an expert in ...

Or maybe I missed something?

trans has changed the build system and the organization to deal with  
the libxslt issues and rake muck. The builder is task/setup, the more  
detailed tasks require you to install ratch.

Okay.

So would task/test be the way to run tests?

Can you currently successful do a task/test? Even with ratch (0.4.1) that
errors out for me.

Steven,

your explanation text looks excellent - clear and some useful examples.

I had only a couple of minor comments - the line "strings in the form like
above" is perhaps a bit awkward. Maybe it would be better to just give an
example, i.e.:

strings in the form "prefix:href"

Also, both of the questions you pose should have a question mark at the end,
i.e.:

* How do I match nodes that use the default namespace prefix?
* How do I match particular nodes within any namespace?

I hope these comments are useful, and apologies for not sending them in the
form of a proper patch, but I'm labouring under the threat of a rapidly
approaching deadline.

Subject: [libxml-devel] finally closing in on the new build
Message-ID: <9ddcb8d9-fbb3-4d37-ac2e-d88e6963473a@k2g2000hse.googlegroups.com>

Hi All,

Let you all know, I'm finally progressing on the build process. I sat
down last week determined to get this straightened out (it effects not
only this project, but a number of others too). After a lot of
deliberation I've nailed down the design and have transformed my
entire code base to suite. So I will have the build processes working
very soon --with the exception of win32 cross-compile for the moment,
b/c I accidentally deleted that script. :-(

The main insight I had is that there are really two sets of build
tasks. One that end-installers need access to, eg. compiling,
installing, rdoc generation and testing; and another set that is for
project admins, eg. publishing the website, packaging and pushing new
releases. To suite this, I simply converted the end-installer oriented
tasks in Ratch to pure Ruby and adopted them for Libxml. You can now
find them in the task/ directory in trunk.

The admin tasks on the other hand (which also include end-install
tasks) I reformulated into a simple "monolithic" project --thus
killing the original notion of Ratch (a collection of ruby-based batch
files). This new application is largely the resurrection of my earlier
work (reap). I will have an early release of the new  app out in a day
or two. With it, it is simply a matter to filling out the needed
metadata (yaml) files and calling the desired bin command. At the
moment there is an admin/ directory in trunk that house the old admin-
oriented tasks. Don't bother with these until I report having finished
the transition.

Btw.. I am getting a segfault on one file:

  $ task/test tests/tc_xml_node_copy.rb
  Loaded suite task/test
  Started
  ./tests/tc_xml_node_copy.rb:35: [BUG] Segmentation fault
  ruby 1.8.6 (2007-06-07) [i486-linux]

  Aborted (core dumped)

Message-ID: <860f9f23-fb01-4fab-8e28-360e7a562ee4@l1g2000hsa.googlegroups.com>

I was putting off posting this but I've decided to cover all bases.

I'm using the libxml ruby bindings under windows courtesy of the
compilation available from http://www.movesonrails.com/articles/2007/10/09/libxml-ruby-and-windows

However, when using the library, I'm getting an error, which appears
to intermittent.

"This application has requested the Runtime to terminate it in an
unusual way.
Please contact the application's support team for more information."

Googling this error refers to a whole lot of Microsoft related errors
which leads me to believe that the something has happened during
compilation of library. On the off chance that this error has happened
to someone else, please reply so that I don't feel inclined to try and
compile xmllib using Visual Studio myself.

The error appears to be intermittent in that if I have some code that
parses an XML file, loads a schema, validates against the schema and
then does some simple dom traversal, then I will get the error about 2
out of 5 times.

If I load another XML file further into the program, then I will
likely always get the error, and the chances are it stuffs something
up.

Cheers to anyone who is familar with this.

Subject: [libxml-devel] prepping libxml2 for Ruby 1.9?
Message-ID: <479F7792.20406@intertwingly.net>

Two things:

I'm trying to port a number of projects to Ruby 1.9.  Current status can 
be seen here:

http://intertwingly.net/projects/ruby19/logs/

I'd like to try libxml2, presuming that people would be interested in 
accepting patches to make this work under 1.9, while continuing to work 
under 1.8.

The second thing is that I first tried to build it under 1.8.  What I 
get is:

$ rake
(in /home/rubys/svn/libxml)
rake aborted!
No such file or directory - ext/xml/libxml.h
/home/rubys/svn/libxml/Rakefile:18:in `read'
(See full trace by running task with --trace)

Did I miss a step?

OK, that builds a .so file.  What setup do I need to run tast/test?  I'm 
getting a lot of Error loading: tests/tc_* messages currently.

It would be nice to enumerate all the extra debian/ubuntu packages
needed to compile libxml2-ruby.
So far I know of:

  libxml2
  libxml2-dev
  libz-dev

What are the others?

Ah... in task/test change the line:

  $LOAD_PATH.unshift(File.expand_path('ext/libxml')) unless live

to:

  unless live
    $LOAD_PATH.unshift(File.expand_path('ext/libxml'))
    $LOAD_PATH.unshift(File.expand_path('lib'))
  end

BTW, to compile and install it is:

  $ task/setup

This is a minor variation on Minero Aoki setup.rb, so anything you
could do with setup.rb you can do with task/setup.

Thanks!

With the attached patch, I've the following sequence works on Ruby 1.9, 
revision 15360 (the latest HEAD):

   rake clobber
   rake compile
   rake test

The patch should not be applies as is, as the rename of util.h to 
ruby/util.h is a breaking change.  Should be easy enough to handle in 
extconf.rb.

My goal is to keep a watch on Ruby 19 and libxml2 to ensure that neither 
commits any changes that breaks the other.  More details can be found here:

http://intertwingly.net/blog/2008/01/31/Ruby-CI-Efforts

Let me know if you commit these changes, or how you want the extconf 
changes to be handled, as once basic Ruby 1.9 support is in place, I 
will add libxml to my list.

Subject: [libxml-devel] Project protocol
Message-ID: <9FB5DCE5-C5D7-415A-AAB8-3120F4273280@3skel.com>

My thanks to all of you for using, discussing, reporting and  
contributing to the ruby-libxml extension. As more people become  
involved and as the quantity of contributions and issues grows, it has  
become more difficult to keep track of what needs to be done. With  
this in mind, the following protocol is necessary for better execution:

Non-developer:

1. the libxml-devel mailing list is for support and discussion
2. Feature changes, bug reports, patches must be submitted to the  
tracker at http://rubyforge.org/tracker/?group_id=494

Developer:

1. The trunk must always be in working order.
2. Narrow scoped bug fixes may be applied directly to the trunk.
3. Each developer should use a self named branch (i.e. danj-devel) for  
making larger changes that may result in prolonged brokenness. The  
developer should track the trunk and merge as required.
4. Larger branch based changes should be packaged into Release  
Candidates using a change name and the SVN number for public  
evaluation. i.e. xpath-1234 or build-1234.
5. Successful RC evaluation should result in a merge back to the  
trunk, assignment of a release number, then publication.

I hope this will make it easier to apply consistent and productive  
time slices for continuing work on the code base. If you find a  
problem with anything said here or something omitted, please discuss.

This entices me. The MRI internals (esp. the GC) are the biggest  
obstacle to making this library work and I am beginning to really hate  
them. I've even had this delusion that making this library work with  
Subtend may enable effective repair of outstanding faults more easily  
than trying to do it under MRI. Then I have this shimmering vision of  
dumping the whole code base and just writing an FFI interface.
