Random XML Parsing - using Perl
Given the XML:
Code:
 
<?xml version="1.0" encoding="UTF-8"?>
<reference>
<refbody>
<section>
<p>
<ul>
<li><xref href="file1.dita#anchor" /></li>
<li><xref href="file2.dita#anchor" /></li>
</ul>
</p>
</section>
<section>
<p>
<xref href="file3.dita#anchor" />
</p>
<p>
<xref href="file4.dita#anchor" />
</p>
</section>
</refbody>
</reference>

I would like to get a list of xref href values:
Code:
href="file1.dita#anchor"
href="file2.dita#anchor"
href="file3.dita#anchor"
href="file4.dita#anchor"


I've used Perl XML::Simple, but it requires that I know the document structure of the document and since these xrefs can occur anywhere in the document, I'm not sure how to handle this. I have several files to process so any assistance you can provide would be helpful.

cgi::xml

XML(3pm)						User Contributed Perl Documentation						  XML(3pm)

NAME

       CGI::XML - Perl extension for converting CGI.pm variables to/from XML

SYNOPSIS

	 use CGI::XML;
	 $q = new CGI::XML;

	 # convert CGI.pm variables to XML
	 $xml = $q->toXML;
	 $xml = $q->toXML($root);

	 # convert XML to CGI.pm variables
	 $q->toCGI($xml);

DESCRIPTION

       The CGI::XML module converts CGI.pm variables to XML and vice versa.

       CGI::XML is a subclass of CGI.pm, so it reads the CGI variables just as CGI.pm would.

METHODS

       $q = new CGI::XML
	   creates a new instance of CGI::XML. You also have access to all of the methods in CGI.pm.

       $q->toXML([$root])
	   where $root is an optional parameter that specifies the root element. By default, toXML will not return a root element.

       $q->toCGI($xml)
	   where $xml is the XML you would like to convert to CGI.pm parameters. Values in the XML will overwrite any existing values if they
	   exist.

NOTE

       CGI::XML does not currently handle multiple selections passed from HTML forms. This will be added in a future release.
