Sorry for the late reply, just got back in the office today. On getting
rid of the =1, I don't believe we can do this in a schema. I'll check but
I'm pretty sure it's a no go for that and the delimiter.

You could do it on a map to strip off the first X characters, or
programatically strip them in orchestration but either are going to effect
performance.

Is there another way to get the data besides doing a get? Something that
would post the data into BizTalk as XML?

| Larry,
|
| I can now confirm that using a custom pipeline and the flat file
| disassembler I am able to deliver a document to my orchestration. The
last
| issue I have, though, is that because the string that is arriving in is
the
| format param1=1&param2=2&param3=3 etc I obviously only want the values 1,
2
| and 3 to be copied into the xml message into the elements param1, param2
and
| param3 respectively. I have set the delimiter in the schema to be &,
however
| and this means that the data that appears in the XMl is actually
| <param1>param1=1</param1> etc. Is there a way of specifying the flat
file
| extensions to the schema such that I can lose the param1= part of the
data
| stripped out? Or do I need to have a map on the outward end of the
receive
| pipeline with some string manipulation functoids in it? I'm getting a
bit
| worried about the performance of all of this (my system is running really
| slowly) and so would rather avoid adding another map if possible.
|
| Thanks again
