Query XML messages by Property Path
I need to query my messages and filter by a XML node.
In the message viewer it would be Critetion Type = 'VDoc Property Path' and class = 'Enslib.Edi.XML.Document'.
At the moment my query looks like this
where doctype = 'avc:mydoctype'
I need then to look for 'HeadNode:SubNodeValue'
Anyone who could help me out with this?
