Hi,
yes, you can insert an On Exception Goto step before the XML handling steps and direct the script to a labeled step.
Like this:
1. On Exception Goto (Label ALTERNATE)
(...)
5. document = Create XML Document
6. // do something with the document
7. End // regular execution stops here
(...)
10. label=ALTERNATE Play Prompt("Please call back later.wav")
The above script will skip to line 10 if the document is not available, but will continue at line 6 if the document reads alright.
What exception to catch? Probably com.cisco.doc.DocumentIOException, or, if you want to be on the safe side, just catch com.cisco.wfapi.WFExecutionException.
Note that the Create XML Document step does not issue any document handling command, it just creates an internal reference - so the actual HTTP request goes out later, probably when doing a Cache Document or a Get XML Document Data step.
