<?xml version="1.0"?>

        <Quantity>100</Quantity>
    </StockMovementData>
</StockMovementDataRequest>

Any thoughts?

Solution

Use Mule Splitter to split xml

    <splitter expression="#[xpath3('//StockMovementDataRequest/StockMovementData',payload,'NODESET')]" doc:name="Splitter"/>        
    <mulexml:dom-to-xml-transformer doc:name="DOM to XML"/>

To aggregate the payload after splitter, use aggregator

<collection-aggregator doc:name="Collection Aggregator"/>
