Your first challenge is to specify this more precisely.
In early drafts of the XQuery specification there was a function called
filter() which was a bit like this, but it got taken out because no-one was
able to write a precise specification of what it was supposed to do.
Sketching out an example isn't good enough. Start by producing a dozen
examples: For example, what output do you want if one of the documents is
<a><b/></a>
and the other is
<b><c/></b>
then generalize from the examples to define the actual rules.

Subject: [xsl] XSLT Filtering based on defined XML
Hi All,
Is there an elegant pattern via xslt to filter out an existing source
xml document based on the contents of another filter xml document?
For example:
Source xml doc:
<Root>
<Node1>
<Node11>
<Node111/>
</Node11>
<Node12/>
<Node2>
...
Filter xml doc:
<Root>
<Node1>
<Node111/>
</Node1>
</Root>
Desired results:
<Root>
<Node1>
<Node111/>
</Node1>
</Root>
Now the issue that I'm dealing with is that the filter xml doc is
dynamic. That is, it can be different for any given xml source doc
configuration based on what another server source specifies. I could
recursively build some dynamic xslt and add apply-templates for each
node and make use of copy and copy-of based on if a node has children
or not and then run that dynamically build transform on the xml doc
source...however, can anybody think of another way to do this?
Thanks in advance!
