Dynamic Context Variable Set Action

I had a requirement where I need to create and store as many context variable depending on the number of elements received with incoming request message. For example, if incoming request messages is.....................

<in>

   <element>100</element>

   <element>200</element>

    <element>300</element>

    <element>400</element>

</in>

 

I needed to create & store context variables like this.. 

 

var://context/TEMP/element1

var://context/TEMP/element2

var://context/TEMP/element3

var://context/TEMP/element4

 

Each context variable contains <element> node. So if incoming number of element nodes are 10 in the request, total 10 context variable needs to be created.

This is the XSL that did work for me.. 

 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dp="http://www.datapower.com/extensions" xmlns:dpconfig="http://www.datapower.com/param/config" xmlns:str="http://exslt.org/strings" xmlns:dpfunc="http://www.datapower.com/extensions/functions" xmlns:regexp="http://exslt.org/regular-expressions" extension-element-prefixes="dp" exclude-result-prefixes="dp dpconfig str dpfunc regexp">

var://context/TEMP/element1

var://context/TEMP/element2

var://context/TEMP/element3

...

..

var://context/TEMP/elementN

('N' decided on the basis of number of incomig elements received (input/element))

<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

  <xsl:template match="/">

     <xsl:for-each select="input/element">

     <!-- Capture position of each "<element>" tag --> 

       <xsl:variable name="i" select="position()" />

       <dp:set-variable name="concat('var://context/TEMP/element',$i)"  value="." /> 

    </xsl:for-each>

  </xsl:template>

</xsl:stylesheet>
