Don't. There are subtleties about the way in which XML is formed
which will conspire to bite you in the ass if you use a non-XML
language.

Using Perl with one of the several XML APIs is fine, of course.

How large is large? XSLT runs pretty fast on a modern system, and what
you want to do isn't exactly rocket science (or if it is, I know any
number of unemployed rocket scientists who can do it for you :-)

This seems to do the job:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                 version="1.0">

   <xsl:output method="xml"/>

   <xsl:template match="items">
     <items>
       <xsl:apply-templates/>
     </items>
   </xsl:template>

   <xsl:template match="item">
     <xsl:if test="contains(property2/code,'Match')">
       <xsl:copy-of select="."/>
     </xsl:if>
   </xsl:template>

</xsl:stylesheet>
