comparing XML streams / nodesets

Hi Y'all,
I have a question. I've got an XML document containing the following
nodeset:
<rootnode>
<childnode>
<grantchildnode1 />
<grantchildnode2 />
<grantchildnode3>
<grantchildnode31 />
<grantchildnode32 />
</grantchildnode3>
</childnode>
</rootnode>
Now in XSL, I have a variable that declares which entities are allowed into
certain functions like this:
<xsl:variable name="allowednodes">
<rootnode>
<childnode>
<grantchildnode1 />
<grantchildnode3>
<grantchildnode32 />
</grantchildnode3>
</childnode>
</rootnode>
</xsl:variable>
when iterating through the main XML document, I need to check if the current
node is allowed to pass through to a function.
Essentially, I'd like to say:
<xslt:if test="count(//*//$allowednodes) != 0" />
This ofcourse doesn't work. Does anyone know if and how I can compare the
trees so I can make accurate decisions about allowing a node ???
Thanks in advance!
Regards,
Martijn.
