Javascript: createElementNS not work in IE ?

[mentor]

The following code catch an exception in IE, with number -2146827850

            var xmldoc=XmlDocument.create("1str","2str");
            xmldoc.documentElement.setAttribute('code',code);
            var node;
            try{
                 node=xmldoc.createElementNS('urn', 'condition');
            }catch(e)
            { }

It seems that IE dosn't implement createElementNS function. Is there any way to work around it?

I need your help!

I don't know what you are talking about. I havn't heard about createElementNS function. But if you want to parse xml text, then refer to the code below. Hope it helps.

createElementNS does exist. IE doesn't support it because it can't deal with XHTML properly. Use createElement instead for IE. See this link.
