AJAX deferred should call success on "No Content," even when a Content-Type is specified

[lucas.madar@…]

When a Content-Type such as "text/xml" is specified in an HTTP 204 ("No Content") status, jquery finds a converter for the datastream in the ajaxConvert() function. This ends up calling parseXML, which creates an invalid XML document and jquery throws an error.

In a 204 No Content situation, jquery should not attempt to parse the empty document. Or, parseXML should return an empty document when passed an empty string.

Thanks for taking the time to contribute to the jQuery project! Please provide a reduced test case to help us assess your ticket.

Additionally, be sure to test against the git version to ensure the issue still exists.

Makes parseXML act like parseJSON when given an empty or non-string input: now returns null rather than throwing an exception. Incidently fixes #10527. Unit tests added.

It looks like this has been fixed in 1.7.2. For anyone trying to work around this in a previous version, I found that forcing the datatype to 'text' in an ajax query works.

This is still broken in 1.7.2 when using 'jsonp' dataType.

Replying to anonymous:

This is still broken in 1.7.2 when using 'jsonp' dataType.

jsFiddle use-case please.
