AJAX call - null from responseXML

[Rob Hunter]

I'm running a javascript in IE 11 and it is failing. I try doing the following in code :

var mainObj = this.responseXML;

If I do this :

alert(mainObj)

I get null.

Someone else running it on IE 11 is getting past this and mainObj prints as [object].

What should I be doing here? Should I somehow parse responseText instead? I don't want to start changing all the code referencing mainObj.

Are you returning the correct content type header in the response for XML?

Hey Bear,
Yes, it prints this in the first 2 lines of the perl script that is called :

     print "Content-type: text/xml\n\n";
     print "<?xml version=\"1.0\" encoding = \"UTF-8\" ?>\n";

The remaining xml content is well-formed as well. This all works when "running" the webpage after going directly to it. The issues seem to lie with if an user goes "Back" to the page and the onblur event gets hit for the lookup field. If on the page and entering values and leaving fields it seems to work regardless. Coming back to the page it doesn't appear to work. Thanks for the reply as well, appreciate it.

What happens if you use "application/xml" (which is the "more correct" MIME type for xml).
