Thanks Ken. The problem with the above approach is that if there are
3 Loop-N1's
then the output would be:
<corecom:ID>NAEDIBrokerageNAEDIBrokerageNAEDIBrokerage</corecom:ID>
Thats why I was trying to set a flag inside the loop and then return a Single
value.
Then you *don't* need the loop at all:
<xsl:template name="getOrderSource">
<xsl:choose>
<xsl:when test='/ns0:Transaction-850/ns0:Loop-N1/
ns0:Segment-N1/ns0:Element-66 = "21"'>NAEDI</xsl:when>
<xsl:otherwise>NAEDIBrokerage</xsl:otherwise>
</xsl:choose>
</xsl:template>
In XPath when you address a set of nodes as an operand in a test, the
test is repeated for every member of the node set until either a
true() value is returned by any member (you aren't told which), or
until the node set is exhausted and a false() value is returned.
I hope this helps.
