• Here's the code we're using to fill out the missing responseXML on both Desktop and Mobile:

  var responseXML;
  if (this.responseXML == null) {
      if (typeof DOMParser != "undefined") {
          // Titanium Desktop 1.0 doesn't fill out responseXML.
          // We'll use WebKit's XML parser...
          responseXML = (new DOMParser()).parseFromString(this.responseText, "text/xml");
      } else {
          // Titanium Mobile 1.3 doesn't fill out responseXML on Android.
          // We'll use Titanium's XML parser...
          responseXML = Titanium.XML.parseString(this.responseText);
      }
  } else {
      responseXML = this.responseXML;
  }
  

• I don't have no problem with that.

  var xhr = Titanium.Network.createHTTPClient();
  xhr.onload = function(e) {
    Ti.API.info(this.responseText);
  }
  xhr.onreadystatechange = function() { }
  xhr.open('GET','http://twoism.posterous.com/rss.xml');
  xhr.send();
  

  and got the entire rss feedback

• Make sure the Content-Type of the response is "text/xml" or "application/xml"

• Brion's answer almost solved my problem.

  I also always have an empty responseXML, but also an empty responseText! (APIs 2.2, Ti 1.5.0)
  Fortunately my responseData was containing the right response so I could use it.
  So if responseText is also null, use responseData.toString() instead.
  Then Brion's code does the job.

  It worked for me.
