in the above xml I need to filter out the condtion for PARTNER_Q. if PARTNER_Q =WE then pass the value of related NAME1 field value to the target.
I have tried below XSL code but not able get the correct logic for filtering
<xsl:variable name="vPartnerfunction" select="$nodes_in/PARTNER_Q"/>
<xsl:variable name="vName" select="$nodes_in/NAME1"/>
<xsl:choose>
<xsl:when test="$vPartnerfunction = 'WE'">
<xsl:value-of select="$vName"/>
</xsl:when>
</xsl:choose>
Please help me out on this.
In the output only i should get the below value
<NAME1>Domestic US Customer 1</NAME1>

The result you show can be produced quite easily by:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/DELVRY07">
<xsl:copy-of select="IDOC/E1EDL20/E1ADRM1[PARTNER_Q='WE']/NAME1"/>
</xsl:template>
</xsl:stylesheet>
However, if there are more than one E1ADRM1 element that meets the condition, the result will be an XML fragment - not a well-formed XML document.
