Creating XML Node Sets From A Delimited String In BPEL

Sometimes we need to create a custom node set from a delimited string value. The following is the one of the way to create the same.

• Bring an Assign activity and add a create-nodeset-from-delimited-string function to the target node and put the parameters as mentioned below.
• First parameter : qname (This is the element name which is generate from the deliminated string)
• Second Parameter : Delimited String
• Third Parameter : Delimiter
• It will generate the number of delimited sting entities to the same number of first parameter element node set. 
• We can copy the whole node set using copy list operation in an Assign activity.
• In the below example the function generate the same number of result element node set as in the input parameter has the number of words separated by comma(,).

For Example : 

<assign name="AssignInput">

      <bpelx:copyList>

        <bpelx:from expression="oraext:create-nodeset-from-delimited-string('{http://xmlns.oracle.com/DelimitedStringDemo}result'

        ,bpws:getVariableData('inputVariable','payload','/client:process/client:input'),',')"/>

        <bpelx:to variable="outputVariable" part="payload"

                  query="/client:processResponse/client:result"/>

      </bpelx:copyList>

    </assign>
