I was able to get it to work by using a variable to pass the value of the
SubscriptionID and inserting a string function within the key function. Why
didn't it work without the string function? - Maria
<xsl:key name="MappingKey" match="Subscription/WDBillerID"
use="../SubscriptionID"/>
<xsl:variable name="SubID"
select="/PresentationData/PageSpecific/SubscriptionList/Subscription/Subscri
ptionID[1]" />
<xsl:template match="Biller">
<option>
<xsl:attribute name="value"><xsl:value-of
select="MappedBillerID"/></xsl:attribute>
<xsl:value-of select="MappedBillerName"/>
</option>
</xsl:template>
<xsl:apply-templates select="//Biller[WDBillerID = key('MappingKey',
string($SubID))]"/>

Subject: Re: [xsl] Using keys to filter nodesets
Hi Maria,
One reason your filter isn't working may be if the XPath
/PresentationData/PageSpecific/SubscriptionList/Subscription/SubscriptionID[
1]
returns every SubscriptionID in the document (the predicate [1] ensures,
here, only that the SubscriptionID is the first child of its parent; maybe
this is true of all of them. Passing a node-set as the second argument of
key() returns all the nodes matching the key with values in that node-set.)
If the intent of your template match is to match only that Biller whose
WDBillerID is the same one (same node, not just same value) returned from
the key using the value of the first SubscriptionID in the document, you
could try
match="Biller[generate-id(WDBillerID) =
generate-id(key('MappingKey',/descendant::SubscriptionID[1]))]"
If that isn't your intent, you may want to clarify what exactly you're
trying to filter and how, with a sample of the source data we could look at.
Cheers,
Wendell
