Brightman MkhwanaziSubject: xpath to compare two values from one xml
Author: Brightman Mkhwanazi
Date: 09 Nov 2010 10:10 AM

I have an xml that i need to process only when the header record is different from the values in the detail record.
The header record repeats and the detail record repeats. I want to only process the record once it happens that the values from the detail record are different from the header record.

I want to compare the two lang values using xpath.

/root/input_data/hdr/lang != /root/input_data/dtl/data/lang

I have attached the xml document.


UnknownTestData.xml
TestData.xml

Brightman

You should use positional predicates to compare precisely nodes and not
node sets

<xs:if test="/root[1]/input_data[1]/hdr[1]/lang[1] != /root[1]/input_data[1]/dtl[1]/data[1]/lang[1]">

<xsl:apply-templates/>

</xs:if>

Hope thia helps
