pub.list:appendToDocumentList operates over IData (document). To use it you need to create this document.

Is your XML structure static?
If yes create a document on IS that resembles your XML structure, then (assuming you have your XML in a string):

1. convert string to IData (document) using:

   • pub.xml:xmlStringToXMLNode
   • pub.xml:xmlNodeToDocument

2. Use pub.list:appendToDocumentList to add new element to e.g. <B> list

3. Convert document back to string using pub.xml:documentToXMLString

If no you still need to create a document in the pipeline:

and then use pub.list:appendToDocumentList:

Ultimetly if required, convert document to string using pub.xml:documentToXMLString
