Problem creating useful column names using constructor

It would help if you could show us what the result from your WatchListGuidIn mashup looks like and what you are expecting as output.

Hi,

as Sara said it's a bit hard to see what the problem is without knowing for sure the output from the <invoke> and what you are actually getting at the moment, but I'm taking a stab in the dark here that the problem is the way you are accessing the node content in your <constructor> statement. Here's a mocked up test I did using your emml. It produces what I think it should if you modify the constructor  to include the ..../text() when building your Name and Address nodes. Try it to see if this works or post back examples of the output/expected results. Cheers, Innes

and it produces:

</result>
