Request] response XML contains error document for invalid XML files
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b4) Gecko/20050910 SeaMonkey/1.0a Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b4) Gecko/20050910 SeaMonkey/1.0a XMLHttpRequest fails to load an invalid XML file >6kb. This happens when the server sends contentType=text/xml and the file is not valid XML. All version before Gecko 1.8 work fine here and return responseXML=null and responseText with the contents. One could argue that this is not a bug but a feature because the server sends the wrong header. But the problem is that sometimes we have no control about foreign servers. Reproducible: Always Steps to Reproduce:
If it's just failing without hanging the browser or crashing etc .. we should not be worried. Does it affect something else for you or this is not big deal ?
Why we shouldn't be worried? a) That's a regression and b) we have no chance to load a document once the server sends text/xml by mistake

Could you attach / point to a testcase please? I couldn't reproduce the bug easily.
This is true for both 1.8 branch and trunk.

Summary: XMLHttpRequest doesn't load invalid XML files → [XMLHttpRequest] responseXML contains error document for invalid XML files
This is alert(r.responseXML.documentElement.textContent). r.responseXML should have been null.
Btw, responseText does not contain the error document but the real response.

Gecko has this old feature where XML parser outputs a document with error info if parsing fails. This is wrong per spec and other implementations Test cases: http://w3c-test.org/web-platform-tests/master/XMLHttpRequest/responsexml-media-type.htm http://w3c-test.org/web-platform-tests/master/XMLHttpRequest/responsexml-non-well-formed.htm
This bug seems like a dupe of bug 289714, which was just fixed. The web platform tests in comment 8 are now passing, and XHRs made by web content for invalid XML documents will now give a null responseXML instead of a <parsererror> document (and the parsing failure will be logged to the web console).
