This solved it nicely--thanks George. It will give me
people who don't have any documents at all, but that's
actually OK for my needs--I just added that caveat
last-second because I (incorrectly, it turns out)
thought it might simplify matters.

The following XSLT 1.0 code *works*, but I think
it
can be greatly simplified--I just don't know the
construct needed for the simplification.
Given an XML such as this:
<data>
<documents>
<document id="1"/>
<document id="2"/>
</documents>
<persons>
<person>
<name>Chris</name>
<document relid="4"/>
<document relid="7"/>
</person>
<person>
<name>John</name>
<document relid="2"/>
</person>
</persons>
</data>
I want to list all people who *have* documents but
do
*not* have at least one document that is in the
<documents> list. For example, Chris above has no
documents in the <documents> list (relid=4 and 7
aren't there), so he would get listed, but John
above
wouldn't, because his "2" is in the list.
This is what I've done (pseudocode, so might have
minor errors):
<xsl:for-each select="/persons/person">
<xsl:variable name="v_DocumentFound">
<xsl:for-each select="document">
<xsl:variable name="v_relid"
select="@relid"/>
<xsl:if test="count(/documents/document[(_at_)id
=
$v_relid]) > 0">
<xsl:text>(document found)</xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:if
test="not(boolean(translate($v_DocumentFound,
' ', '')))">
Document was not found for <xsl:value-of
select="name"/>
</xsl:if>
</xsl:for-each>
In other words, I stuff a variable named
$v_DocumentFound with text each time a document
match
is found, then check whether the variable is empty
to
see whether or not I need to report something.
Is this the right way of doing what I am trying to
accomplish--or is there a simpler method? Mine
seems
verbose, like I'm missing something obvious.
Thanks,
Glen
