Subject: Passing XML document from Perl + exslt:node-set causes weird behavior
This is a copy of GNOME Bugzilla bug #562302 filed by Alexander Schepanovski against libxslt: https://bugzilla.gnome.org/show_bug.cgi?id=562302 ------------------------------------------------- Perl code making trouble: #!/usr/bin/perl use XML::LibXML; use XML::LibXSLT; my $parser = new XML::LibXML; my $xslt = new XML::LibXSLT; # registering function my $doc; sub cfg { my $xml = q~<?xml version="1.0" encoding="utf-8"?><xml_storage></xml_storage>~; return $doc = $parser->parse_string($xml); } XML::LibXSLT->register_function("urn:perl", 'cfg', \&cfg); # loading and parsing stylesheet my $style_doc = $parser->parse_file("skeleton.xsl"); my $stylesheet = $xslt->parse_stylesheet($style_doc); # performing transform my $source = new XML::LibXML::Document; my $results = $stylesheet->transform($source); # writing result open F, ">result.xml" or die; print F $stylesheet->output_string($results); close F; Where skeleton.xsl is: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:exslt="http://exslt.org/common" xmlns:perl="urn:perl" exclude-result-prefixes="exslt perl"> <xsl:variable name="xml_storage" select="perl:cfg()/xml_storage" /> <xsl:variable name="page-data-tree"> <title><xsl:value-of select="$xml_storage"/></title> <crumbs> <page><url>hello</url></page> <page><url>bye</url></page> </crumbs> </xsl:variable> <xsl:variable name="page-data" select="exslt:node-set($page-data-tree)" /> <xsl:template match="/"> <result><xsl:value-of select="$xml_storage"/></result> </xsl:template> </xsl:stylesheet> Result is <?xml version="1.0"?> <result>bye</result> It seems that value of $xml_storage varies depending on its use in diffrent part of xsl stylesheet. It also depend on its true value passed from perl. Varying stylesheet and xml document passed from perl, you can even get segfault.

Hi Nick, this link is broken - even in the original message: https://bitbucket.org/nwellnhof/perl-xml-libxslt/commits/7bfbae8885464b0dc70ae28c715507c6d70854fe Plus, the example program suffers from many bad idioms (which is fixable, but still). Regards, -- Shlomi Fish.
