| Hi John,
You could try adding some debuc code, just to double check that you are
getting the XPath stuff right.
Try:
System.Daignostics.Debug.WriteLine (aSalesOrders[i].OuterXml);
in the loop, then run the orchestration with VisualStudi attached to the
BizTalk service. This should give you some insite as to what's going on in
the orchestration.
Regards,
Alan
