I am having difficulty retrieving XML content using an XMLHttpRequest from Mozilla FireFox. I have a php page which generates XML to be retrieved by a XMLHttpRequest. I have had cross browser success in retriving plain text. However IE retrieves the XML content successfully without any problems. In the case of FireFox not only is the responseXML not set but neither is the responseText ruleling out the possibility of just parsing the text into XML.
I wonder if there is a known problem or issue with retrieving XML using FireFox and any possible workarounds.
