I've noticed that with FF, you cannot see the HTML content of an AJAX response while traversing over its child elements. The only way you can see the innerHTMLish value is to use responseText instead of responseXML. However, IE does support this through a property namely "xml", which returns the exact XML content of the current Node. I think this is not an issue with AJAX, but in fact it relates to DOM implementation. Is there a way for me to see some kind on innerHTMLish value of a some node using Firefox? Thanks in advance.
