| Sorry, I should have explained that “XPath” is a reserved word in XLANG (i.e.
inside the Orchestration). It is a short cut to get access to XML Documents
and Messages inside the Orchestration.
So, the exact code that works outside the Orchestration should not look the
same inside the Orchestration.
You can find some more information on using XPath inside the Orchestration
by searching the help guide for: “Using XPaths in Message Assignment”. The
same code can be used to do XPath querries inside an Expression Shape as well.
Let me know if you have additional questions.
