RE: [xsl] Problems selecting the right nodes.

["Kienle, Steven C [PGRD/0200]" <steven.c.kienle@xxxxxxxxxxxxx>]

I'm not sure if this will fit the bill, but it does return the correct
results with your sample below.

<xsl:template match="service">
    <xsl:if test="/root/branch[not(service/@id = current()/@id)]">
        <xsl:value-of select="@id" />
    </xsl:if>
</xsl:template>

Basically, this matches the service nodes and only executes the value-of
when the exists a branch which does not have a service with the same @id as
the current service.  Because it is processing nodes, it possible that you
could have some duplication, which you may not want.  You might be able to
use this as a starting point.

I have a nodeset or arbitrary length that contains a set of tags which 
look something like:

<branch id="br1">
   <service id="service1" />
   <service id="service2" />
   <service id="service3" />
</branch>
<branch id="br2">
    <service id="service1" />
    <service id="service4" />
</branch>

Now what I want is a nodeset that contains (uniquely) all the services 
that do not occur in all the branches. In this case I want service 2, 3 
and 4 but not 1
