I am trying to get a node set where a child element of each node should
have a unique value. I think I can do this with XPath, but can't figure
out what how to filter it.
Hi,
The most common way to filter out unique nodes is with keys.
Try something like this:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output indent="yes"/>
<xsl:key name="description" match="*[(_at_)QText='Analysis Description:']"
use="."/>
<xsl:template match="/">
<xsl:copy-of
select="//*[generate-id(key('description',.))=generate-id()]/.."/>
</xsl:template>
</xsl:stylesheet>
outputs:
<SS_Analysis>
<Q_2676_2_Analysis_Descri QText="Analysis
Description:">2,3,7,8-TCDD</Q_2676_2_Analysis_Descri>
</SS_Analysis>
<SS_Analysis>
<Q_2676_2_Analysis_Descri QText="Analysis Description:">601/602
Volatiles</Q_2676_2_Analysis_Descri>
</SS_Analysis>
<GW_Analysis>
<Q_3692_2_Analysis_Descri QText="Analysis
Description:">2(2-Butoxyethoxy)ethanol</Q_3692_2_Analysis_Descri>
</GW_Analysis>
<DW_Analysis>
<Q_5066_2_Analysis_Descri QText="Analysis Description:">507
Pesticides</Q_5066_2_Analysis_Descri>
</DW_Analysis>
