The problem is that the XML document is based on a DTD (to which there is a link in the DOCTYPE declaration) that does define 'id' as being of type ID, but doesn't allow xml:id, i.e. I can only rely on the 'id' attribute to access my elements. But as you pointed out (to my despair) browsers are not DTD aware when parsing responseXML. Why is that so?? Do you know if there's anything new on that front? Thx for the good post and, should you be able to help me, for your support! :-) pagod Hi,

Could you offer any tips/insights? I tried accessing http.responseText using and responsehandler e.g.
var x=http.responseText;
and then getElementById().innerHTML, e.g.
var y=x.getElementById(’y').innerHTML;
but I get “undifined is null or not an object”.
Could you offer any tips/insights?
