Subject: [Nokogiri-talk] parsing html with tabs
Message-ID: <20090609181740.3c218afe@der-dieb>



I have some html that looks like the following.

<pre>
<a href="jeos-8.04.1-jeos-i386.iso">jeos-8.04.1-jeos-i386.iso</a>
01-Jul-2008 04:59           104361984 <a
href="ubuntu-8.10-desktop-amd64.iso">ubuntu-8.10-desktop-amd64.iso</a>
14-Nov-2008 14:53           732989440 
</pre>

A basic directory listing with links to the files, timestamp and
size. I did the following to get the file names:

doc.search('a').map { |link| link['href'] }

But I also need to get the size which is essentially in the third
column. How would I go about doing this in nokogiri? Any/all advice
would be appreciated.

Thanks!

-Joe

use .next_sibling something like:

l['href'],l.next_sibling.to_s.split(" ")[-1] ] }

Subject: [Nokogiri-talk] style,
	script and comments getting scrubbed in before/after
Message-ID: <4A319608.2080601@gmail.com>

Hi,

I'm trying to add a chunk of html to the beginning/end of a node with 
before/after methods in Node or NodeSet any style,script tags are 
scrubbed of their contents, though attributes are still available. Also, 
I noticed that html comments are also ignored. Something like this:

|doc.xpath("//head/*[1]").before("<script>var xb=25</script>")

And I try to display it, this is what I get:

||hdoc.xpath("//head/*[1]")
=> <script></script>|

Am I missing something?

Thanks,
Vamsee.

Your xml file probably has a default namespace declared in the root
node.  When you're using XPath queries, you *must* specify the
namespace.  The same is not true for css selectors.  CSS selectors
will add the namespace for you.

Try comparing this:

  doc.xpath('//xmlns:club')

to this:

  doc.css('club')

Hope that helps.

hi list, i have a question on how to actually write attributes to
nodes with nokogiri. i found a way on how this was done in hpricot
http://seancribbs.com/tech/2008/05/19/modifying-attributes-with-hpricot/

what would be the nokogiri way of doing this? especially how to alter
and re-read the doc?

thanks!

Hi,

I reported this issue on GitHub, and also asked on this list and even on 
stackoverflow. I didn't even get one reply. I'm mystified by the 
silence. Can anybody answer me why Node and NodeSet.before and after are 
cleaning out all the content within script and style tags in the 
supplied raw html? Also, the supplied html doesn't get processed 
properly if it has html comments embedded  in it.

Thanks,

Message-ID: <52555.216.185.71.24.1245079825.squirrel@webmail.harte-lyne.ca>

I have been reading about xpath and xml and I have a small amount of
experience with it.  However, I clearly lack sufficient exposure and
experience with xml to discover the answer to my questions on my own
so I would appreciate any help that this list can provide.

I am testing a Rails project and I wish to extract from a displayed
page the contents of a set of particular td cells in a row.  The
page layout, abbreviated, looks somewhat like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<body>
  <table  id="forex_index_table" ...>
  <thead>...</thead>
  <tfoot>...</tfoot>
  <tbody>
    <tr ....</tr>
    ...
    <tr class="forex_rate_line" id="...>
      <td...>...</td>
      <td class="currency_quote">USD</td>
      <td class="effective_date">2009-04-01</td>
      <td class="source">CABC</td>
      ...</tr>
    <tr class="forex_rate_line"...

I am trying to thread my way through nokogiri's documentation to see
how I parse this.  What I wish to do is to check the .text of each
tr node that contains td nodes with class attributes set to
'currency_quote', 'effective_date', and 'source', obtain the text
values associated with each and decide from that combination whether
this row needs to be considered further.

I figured that this is where I would start (in the Rails console:

doc = Nokogiri::HTML(app.body)
=> ... that gives me the document body

next I load the table as a node

t = doc.at('table')
=> ... this seems to work as I imagine

I have looked at the #traverse method and I suppose nesting the the
rows something starting like this might produce something useful

t.traverse do |r|
  ...

But at this point I have no clue as to how to process the rows so as
to obtain those containing cells whose class matches the
requirements.  Once I have these then, assuming that c contains the
requisite td node then c.text should give me the data.  But getting
them seems to hinge on the value of the class attributes.

On the other hand, I greatly fear that I am totally blind to a more
direct way of accomplishing the same thing.  At the moment, my only
requirement for xml is to assist in testing. I can brute force this
into a form that I can test using other means but i would very much
like to use this opportunity to discover how this is supposed to
work.

If I am asking too basic a question for this list then I would
appreciate a reference to an online group that can walk me through
this.  I pretty sure that this sort of processing is not very
sophisticated and that it is my ignorance that is the problem.

Okay.  We can translate what you just said in to an XPath query.  What
you're asking for is more difficult with CSS than with XPath, so we'll
stick with XPath for this one.

You want all tr nodes, so start off with this path for selecting all tr nodes:

  //tr

But you need it to have a td child:

  //tr[td]

Further, you need that td child to have a class attribute equal to
"currency_quote":

  //tr[td[@class = "currency_quote"]]

Finally, you actually need three td children to exist each with
different class attributes (I've broken this one up on to several
lines for readability):

  //tr[
        td[@class = "currency_quote"]
    and td[@class = "effective_date"]
    and td[@class = "source"]
  ]

Just feed that in to Nokogiri's xpath method, and you should have the
tr tags you're looking for:

doc = Nokogiri::HTML DATA.read

tr_tags = doc.xpath(<<-eoxpath)
  //tr[
        td[@class = "currency_quote"]
    and td[@class = "effective_date"]
    and td[@class = "source"]
  ]
eoxpath

tr_tags.each { |tr| .... }

You can find pretty much anything in your tree using xpath or css.
Most of my traversal through XML/HTML trees is via XPath or CSS.

I would suggest reading up on XPath here:

  http://www.w3schools.com/Xpath/default.asp
  http://www.w3.org/TR/xpath

Hope that helps!

This is enough plus ones for me.  I will migrate the email addresses
from the rubyforge list to the google groups list.  Once I'm done
updating everything, I'll email this list with the announcement.

Message-ID: <4b6f054f0906150954q4d6c1397g606c2660ef3ef735@mail.gmail.com>

How would I replace a node with it's children?

  node.replace(node.children)

does not work.

In other words I need to "unwrap a node", eg. if I wanted to unwrap <b> in:

  "<a><b><c>C</c></b></a>"

I'd get:

  "<a><c>C</c></a>"

Thanks,
T.

I would do this:

require 'nokogiri'

doc = Nokogiri.XML(DATA.read) { |cfg| cfg.noblanks }

node = doc.at('b')
node.children.each do |child|
  node.parent << child
end
node.remove

puts doc
__END__
<root>
  <a>
    <b>
      <c>C</c>
    </b>
  </a>
</root>

Hope that helps!

We have a ticket open for this now.  I think I've fixed it, but since
I don't have Snow Leopard, do you mind being the guinea pig for this
one?

Just install nokogiri like this:

  $ sudo gem install nokogiri -s http://tenderlovemaking.com/

You should get version 1.3.1.20090615105405.  That has my Snow Leopard
fix in it.  If it works, I'll commit and close the ticket.

Thanks!

Now I am simple trying to ape what you have told me at the moment. I
suppose this is the consciously incompetent stage of learning.  In
any case this is what I am trying to do in the console:

>> doc = Nokogire::HTML(app.doc)
... stream of consciousness text

>>
?> tr_tags = doc.xpath(<<-eoxpath)
  //tr[
        td[@class = "currency_quote"]
    and td[@class = "effective_date"]
    and td[@class = "source"]
  ]
eoxpath
=> nil

>> end
=> 0
>> y tr_tags
--- !ruby/object:Nokogiri::XML::NodeSet
document: !ruby/object:Nokogiri::HTML::Document
  decorators:
  errors: []

  node_cache:
  - !ruby/object:Nokogiri::XML::Element {}

=> nil

It appears that for some reason this does not work as expected.  The
last time that I ran into this problem it revolved around the
default name space xlmns, but I have no idea if that applies here or
not.

Your assistance is as invaluable as it is generous.  I am very

Interesting.  I tested that xpath against a slight modification of the
example document you sent.  Can you send along the actual document?

If you're using Nokogiri::HTML, namespaces should not bother you.
Nokogiri::HTML is meant for HTML <= 4.01 (IIRC), and just strips out
namespaces.

Thanks!  :-)

Possibly.  This came about from a hack to support ppc and i386 builds
at the same time.  I actually don't think that hack is necessary
anymore, but I need to do some testing.

Ah, there are no td tags that contain the class "currenty_quote", or a
td where the class = "source".

This XPath seemed to work better for me:

doc = Nokogiri::HTML DATA.read

tr_tags = doc.xpath(<<-eoxpath)
  //tr[
        td[@class = "quote_currency"]
    and td[@class = "effective_date"]
  ]
eoxpath
puts tr_tags.length

I've migrated the list to google groups.  The address is here:

http://groups.google.com/group/nokogiri-talk

I tried to add everyone from the current list to the google groups
based list.  Unfortunately, Google flagged me as attempting to spam,
so they are moderating my migration of the list.  So I think you
should either add yourself, or just wait.  I'm pretty sure google will
approve my request.  I will continue to respond to emails on this list
until I see that Google has accepted my request.  Once that happens, I
will shut off mails for this list.

Note to the digest subscribers:  I did not migrate your email
addresses as I don't know what your digest settings are.  Please add
yourself to the Google group.

I've updated all documentation, including the website, and the IRC
channel topic to point at the new list address.

Thanks everyone!

Arggg! I am such a clot.  Of course! I shortened a few things for
the purpose of example and then failed to accommodate those changes
when I received the answer.  I am sorry.

Thank you very much for this.

If I may impose further, is the @class syntax described inside the
nokogiri docs somewhere?  I believe that my lack of facility with
the nuts and bolts of forming syntactically correct expressions is
what is limiting me.  I have just gotten used to .xxxx meaning css
class=xxxx and #xxxx meaning css id=xxxx.  Where does the @ come
from and what is the significance of the leading //?

Again, many thanks.

No problem.  :-)

When you're doing xpath queries, @whatever refers to the attribute
named "whatever".

The leading "//" indicates that you want to search the entire document
starting at the root.  Try to think of xpath kind of like file paths.
"//" is roughly equivalent to "/**/*".

Was that the line:
ENV["ARCHFLAGS"] = "-arch #{`uname -p` =~ /powerpc/ ? 'ppc' : 'i386'}"
in extconf.rb? Yeah, you shouldn't need that for Leopard.

If you need to specify which architectures you want the gem to build  
for, it should be possible to specify on Leopard. Example:
	env ARCHFLAGS='-arch i386 -arch x86_64' gem install nokogiri

See http://developer.apple.com/releasenotes/OpenSource/PerlExtensionsRelNotes/

Yes, this is probably in there, and is probably documented. I will keep 
searching and report back if I find it.

With nokogiri this is much simpler:

doc.css('img').each do |element|
   element['src'] = new_src
end


Vamsee.

hi again list; and thanks a lot for answering my previous question.

another nokogiri question: i need to traverse a doc (XML) and not only
change the node_type on some nodes, but also add some attributes.
it seems when changing the node_name within the loop, the document
seems to get f*cked up -- i think this is when a parent node name is
changed and a child is edited...

any workaround for this?

Can you provide some short sample code that demonstrates the problem?
I can help more when I can actually see what's going on.

Thanks!

Subject: [Nokogiri-talk] How to configure xml.builder to call Nokogiri?
Message-ID: <4A3C0BE7.5090204@gmail.com>

Railsters:

I'm still on the learning curve with exotic partials. I seem to understand that 
a file with the extension *.xml.builder will call Builder::XmlMarkup. If so, how 
to configure it to call Nokogiri::Builder instead?

(CC'd to Nokogiri's mailing list, but I might get a faster turnaround here, + 
that list is now migrating to Google Groups...)

Subject: [Nokogiri-talk] Enterprise Ruby!
Message-ID: <4A3FE5BC.4030705@gmail.com>

Two answers to the FAQ "is Ruby useful in the enterprise?"

Aaron P:

http://github.com/tenderlove/enterprise/tree/master

Jay Levitt:

If you're looking for global enterprise solutions to integrate
distributed systems, at the end of the day, Ruby has the momentum to
leverage the dynamic potential of synergies between your skillsets and
its core competencies on Internet time.  Achieving best-of-breed,
mission-critical componentization utilizing standards-compliant
scalability, it provides an adaptable, standards-based framework to add
value via a fast-track, result-driven development process.

I hope that helps answer your question.
