AjxUtil.xmlToJs can't handle namespaces

[smies]

The AjxUtil.xmlToJs method can't handle namespaces in attribute tags.

The response of a SOAP request:

<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <env:Body>
    <n1:FindAllProductsResponse xmlns:n1="urn:ActionWebService" env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <return n2:arrayType="xsd:int[4]" xmlns:n2="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="n2:Array">
        <item>
          1
        </item>
        <item>
          2
        </item>
        <item>
          3
        </item>
        <item>
          4
        </item>
      </return>
    </n1:FindAllProductsResponse>
  </env:Body>
</env:Envelope>

The result after it is been processed by AjxUtil.xmlToJs (I stripped the whitespaces where I also are having problems with):

{
	Body:{
		FindAllProductsResponse: {
			xmlns:n1:"urn:ActionWebService",
			env:encodingStyle: "http:\/\/schemas.xmlsoap.org\/soap\/encoding\/",
			return:{
				n2:arrayType:"xsd:int[4]",
				xmlns:n2:"http:\/\/schemas.xmlsoap.org\/soap\/encoding\/",
				xsi:type:"n2:Array",
				"",
				item:{
					"1"
				},
				item:{
					"2"
				},
				item:{
					"3"
				},
				item:{
					"4"
				}
			}
		}
	}
}

If you use the eval function on this then it obviously brakes on xmlns:n1 and so on.

I wrote a little fix:

AjxUtil.xmlToJs =
function(node, omitName) {

	if (node.nodeType == AjxUtil.TEXT_NODE)
		return ['"', node.data, '"'].join("");

	var name = node.name ? node.name : node.localName;
	if (node.nodeType == AjxUtil.ELEMENT_NODE) {
		var text = omitName ? "{" : [name, ":{"].join("");
		var needComma = false;	
		if (node.attributes ) {
			for (var i = 0; i < node.attributes.length; i++) {
				var attr = node.attributes[i];
				if (attr.name == "xmlns") continue;
				if (needComma) text += ",";
				var value = AjxUtil.isNumeric(attr.value) ? attr.value : AjxUtil.jsEncode(attr.value);
				var attr_name = attr.name
				var indexdblp = attr_name.indexOf(":")
				if(indexdblp != -1 ) attr_name = attr_name.substr(indexdblp+1)

				text = [text, attr_name, ':', value].join("");
				needComma = true;
			}
		}
		if (node.hasChildNodes()) {
			
			var cnodes = new Object();
			var hasChild = false;
			for (var i = 0; i < node.childNodes.length; i++) {
				var child = node.childNodes[i];
				var cname = child.name ? child.name : child.localName;
	
				var isAttr = AjxUtil.NODE_IS_ATTR[cname] || 
							 (name == "content" && parent.name == "note");
							 
				if (isAttr) {
					if (needComma) text += ",";
					text = [text, cname, ':', AjxUtil.jsEncode(child.textContent)].join("");
					needComma = true;
				} else {
					if (!cnodes[cname])
						cnodes[cname] = new Array();
					cnodes[cname].push(child);
					hasChild = true;
				}
			}
			if (hasChild && needComma) {text += ","; needComma = false;}
			for (var cname in cnodes) {
				
				if (needComma) {
					text += ",";
					needComma = false;
				}
				var repeats = AjxUtil.NODE_REPEATS[cname] ||
							  (cname == "mp" && name == "mp");
				if (repeats) text += cname + ":[";
				var clist = cnodes[cname];
				for (var i = 0; i < clist.length; i++) {
					if (needComma) text += ",";
					text += AjxUtil.xmlToJs(clist[i], repeats);
					needComma = true;
				}
				if (repeats) text += "]";
			}
		}
		text += "}";
	}

	return text;
}

Somewhere in the code there are the lines:
var indexdblp = attr_name.indexOf(":")
if(indexdblp != -1 ) attr_name = attr_name.substr(indexdblp+1)

text = [text, attr_name, ':', value].join("");

They take care of the namespaces by removing them.

I created Web Services in Ms.Net and the result return as below:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<getMasterFilesResponse content="[{&quot;IdentityID&quot;:1,&quot;Code&quot;:&quot;S LS&quot;,&quot;MyName&quot;:&quot;Sales Invoice&quot;},{&quot;IdentityID&quot;:2,&quot;Cod e&quot;:&quot;PYM&quot;,&quot;MyName&quot;:&quot;P ayment Invoice&quot;}]" xmlns="http://www.profrtgroup.com/webservices/" />
</soap:Body>
</soap:Envelope>

it failed to create xmldoc from the above message.
Then i remove <?xml version="1.0" encoding="utf-8"?>, it success....

This occurs only in IE, Firefox is fine.

Help please...

What kind of error do you get when you try with the header?

[sirick]

This will not cause an error from CreateXmlFromString
But error occurred in _check function.

the doc will retrun with 2 childnodes...
one for <?xml .... ?>
and another one for <soap:Envelope ....>

_check function will check for only valid return is only one childnode for doc.

[smies]

I also had problems with the _check method. Because the AJAX xml methods don´t ignore whitespaces there are more elements in the xml document then _check expects. I already opend a tread about that problem.

Maybe you can right a fix for the problem and share the code with us.

[sirick]

The main issue for me is the problem occurs only in IE.

Somebody opend a new thread with the same problem (or is it?). See AjxSoapDoc bug under IE6 only for your answer.
