I don't know how to tell what href is relative to, but even just to get the value of href is a bit gimpy for "processing instructions", which is what <? ... ?> are.
#!/usr/bin/perl -w
use strict;
use XML::LibXML;
my $parser = XML::LibXML->new;
my $doc = $parser->parse_string(<<'EOX');
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href ='abc"efg'?>
<_/>
EOX
foreach my $node ($doc->findnodes('//processing-instruction()')) {
my $name = $node->nodeName;
if ($name eq 'xml-stylesheet') {
# getData is a string like q{type="text/xsl" href="/test.xsl"}
# which is what makes it annoying
my $attr_str = $node->getData;
# manually parse the string like href='abc"efg';
# there might be a better way of doing this
$attr_str =~ m{href\s*=\s*(['"])([^\1]+)\1};
my $href = defined $2 ? $2 : '';
print "$name href: >>>$href<<<\n";
}
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
