I'm not really sure what you mean by "intersect" - it would help to give an
indication of the output you expect. I suspect you mean that you want to
augment document2 by adding the drillDownName corresponding to each
drillDownType. (I'd call that a join rather than an intersection). The
obvious way to do this is to define a key:
<xsl:key name="ddt" match="DrillDown" use="DrillDownType"/>
and then process document 2 by writing:
<xsl:template match="drillDown">
<xsl:copy-of select="DrillDownType"/>
<xsl:variable name="ddt" select="DrillDownType"/>
<xsl:for-each select="document('doc1')">
<xsl:copy-of select="key('ddt', $ddt)/DrillDownName"/>
</xsl:for-each>
</xsl:template>
