[GoogleCodeExporter]

What steps will reproduce the problem?
1. read in feed that has ampersands within data
2. execute jsfiddle with feed
3. parse error on execution

What is the expected output? What do you see instead?

JSON with correctly escaped ampersand to be able to replicate XML feed which 
includes many ampersands within data.
See instead a parse error.

What version of the product are you using? On what operating system and

I've checked it with v1.1.3 
(https://code.google.com/p/x2js/source/browse/xml2json.js) and it looks like 
working for me.

Example with your feed:

     function loadXMLDoc(dname) {
        if (window.XMLHttpRequest) {
            xhttp=new XMLHttpRequest();
        }
        else {
            xhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
        xhttp.open("GET",dname,false);
        xhttp.send();
        return xhttp.responseXML;
    }

    var xmlDoc = loadXMLDoc("447NewDevs.xml");
    var x2js = new X2JS();
    var jsonObj = x2js.xml2json(xmlDoc);

Could you please provide your sample / code where is a problem?

Was testing via the JS Fiddle you built - inputting the XML from in textarea 
for XML field (together with & data)...

Ouch. Now I understand what you mean. You can't enter '&' to that demo, because 
it is not suitable demo for XML escaping. 
You should have valid well formatted XML string or DOM object for input.
For example, this is not valid XML in string form:
"<textNode>First & Child</textNode>". 
Valid and well-formed XML string form is "<textNode>First & Child</textNode>"
If you have manually enterered XML in string form, you should escape it value 
(because it is required by XML standard).

You should escape only XML node value, not full XML document (in a string 
form). 
For example:
"<textNode>First <> Child</textNode>" should be
"<textNode>First <> Child</textNode>"

Well, this is a not x2js issue. It is just about valid XML string formatting :)
Let me know if you had any other questions.

right - I was using &  (not just & as it isn't valid XML)  ... the fiddle   
doesn't work with & values.

Ok, you entered you test data with & in the input or in the HTML window code 
frame (at fiddle)?
You can't do it with HTML window code. Actually I'm just lazy and shouldn't 
have fill textarea in that style (because it's not valid HTML).
If you enter test data with & in the textarea (bottom-right frame at fiddle) 
you will see it's working :)

NP. I'll think about update demo to avoid misunderstandings.
