Ajax's responseXML Error

One thing that I see being asked more and more is why am I getting an error when I try to read the responseXML property. Well the main reason is normally the developer forgot to add the Content Type to set the document to XML. Other reasons is that the server has a problem with XML (I think I have seen this with Apache mainly.) As a result I wrote an article over on my site showing the error and how to correct it using the DOMParser. You can find the article here: http://www.pascarello.com/TestHTMLXMLfromServer.htm. The best solution is to set the Content Type and make sure the server is serving the dynamic XML documents correctly!
