[libxml-devel] Specifying namespace on XPath?

[Paul Dlug]

I think I have a related bug that your patch doesn't fix. If I have a  
document with a DTD declaration specifying a namespace and an  
identical document without it the XPath expression finds the node in  
the document w/o DTD but not with the DTD. The attached test case  
illustrates the problem, to replicate:

1) Run dtdtest.rb, you will see that the test will fail being unable  
to find a node via XML::Node.find()

2) Comment out the ATTLIST spec in a.dtd and re-run, test will pass  
this time (or remove the DTD declaration from the file dtd.xml).
