Creating index Across Multiple XML documents

Hi All,

I want to create an index across multiple XML
documents in order to check the name uniqueness of the
element "Member".

<Member name="">
</Member>

It seems like this one doesn't work.

<xsl:key name="keyname"
match="document('filename')/Member/@name" use=".">


Is there any better way to do that?


Thanks


Dongling
