HTTP_POST_XML error with no/empty response

[mfef]

Hi everybody,

on successful invocation of an asynchronous http-interface, error 66 "XML parse failed at line 1, col 0: no element found" is displayed with RC = -1.
The server returns HTTP 200, there is no response, that's correct. The call is properly processed.

call:

SetError() #66: XML parse failed at line 1, col 0: no element found

Can anyone tell me why it is trying to parse the empty response?

[Scott Klement]

That's what HTTP_POST_XML does... it parses the response with an XML parser.

Use HTTP_POST (or a newer option like http_req) if you don't want it to try to parse the response.
