Starts a streaming HTTP response.


  RETURNS xml.StaxReader


The beginXmlResponse() method starts a streaming HTTP response and returns a xml.StaxReader object ready to read XML from the server.

The Content-Type header must be of the form */xml or */*+xml. For example: application/xhtml+xml.

In case of error, the method throws an exception and sets the status variable. Depending on the error, a human-readable description of the problem is available in the sqlca.sqlerrm register. See Error handling in GWS calls (status).

The int_flag variable is checked during GWS API call to handle program interruptions, for more details, see Interruption handling in GWS calls (int_flag)
