blackberry

I'm trying to port a portion of AJAX code I wrote over to the BlackBerry application's embedded browser. Our base build is 4.6.1 and the RIM documentation claims that XMLHttpRequest's responseXML is available starting with this version. And when I request an XML file from my local server, I get back the responseText (so I know the request is working), but the responseXML is always null. I've made sure the HTTP "Content-Type" header is set to "text/xml" and I am getting the correct data loaded in a web browser. It's just nulling out in the BB web environment. Does anyone know what might be happening?

A backup of using the responseText and piping it through DOMParser is not possible because that object was not added to the BB browser until 4.7.1. So I'm not sure what fallback I have.
