figure out the XPath to make the keys useful.

not sure what you meant by

in that case.

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:key name="o" match="object[property[@name='title']]" use="normalize-space(property[@name='title'])"/>

<xsl:template match="/">
<xsl:copy-of select="
for $m in max(//object[normalize-space(property[@name='title'])='COMPARE']/number(property[@name='version']))
<xsl:variable name="m" select="max(key('o','COMPARE')/number(property[@name='version']))"/>
<xsl:copy-of select="key('o','COMPARE')[number(property[@name='version'])=$m]/id"/>
