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.

1	/**
2	 * Create a new Document object. If no arguments are specified,
3	 * the document will be empty. If a root tag is specified, the document
4	 * will contain that single root tag. If the root tag has a namespace
5	 * prefix, the second argument must specify the URL that identifies the
6	 * namespace.
7	 */ 
8	XML.newDocument = function(rootTagName, namespaceURL) { 
9	  if (!rootTagName) rootTagName = ""; 
10	  if (!namespaceURL) namespaceURL = ""; 
11	  if (document.implementation && document.implementation.createDocument) { 
12	    // This is the W3C standard way to do it 
13	    return document.implementation.createDocument(namespaceURL, rootTagName, null); 
14	  } 
15	  else { // This is the IE way to do it 
16	    // Create an empty document as an ActiveX object 
17	    // If there is no root element, this is all we have to do 
18	    var doc = new ActiveXObject("MSXML2.DOMDocument"); 
19	    // If there is a root tag, initialize the document 
20	    if (rootTagName) { 
21	      // Look for a namespace prefix 
22	      var prefix = ""; 
23	      var tagname = rootTagName; 
24	      var p = rootTagName.indexOf(':'); 
25	      if (p != -1) { 
26	        prefix = rootTagName.substring(0, p); 
27	        tagname = rootTagName.substring(p+1); 
28	      } 
29	      // If we have a namespace, we must have a namespace prefix 
30	      // If we don't have a namespace, we discard any prefix 
31	      if (namespaceURL) { 
32	        if (!prefix) prefix = "a0"; // What Firefox uses 
33	      } 
34	      else prefix = ""; 
35	      // Create the root element (with optional namespace) as a 
36	      // string of text 
37	      var text = "<" + (prefix?(prefix+":"):"") +  tagname + 
38	          (namespaceURL 
39	           ?(" xmlns:" + prefix + '="' + namespaceURL +'"') 
40	           :"") + 
41	          "/>"; 
42	      // And parse that text into the empty document 
43	      doc.loadXML(text); 
44	    } 
45	    return doc; 
46	  } 
47	};

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