function parseXml(xml){    var xmldom = null;    if(typeof DOMParser!="undefined"){       xmldom = (new DOMParser()).parseFromString(xml,"text/xml");       var errors = xmldom.getElementsByTagName("parsererror");       if(errors.length){            throw new Error("XML parse error:"+errors[0].textContent);    }else if(typeof ActiveXObject!="undefined"){        xmldom = createDocument();        xmldom.loadXML(xml);        if(xmldom.parseError!=0){            throw new Error("XML parse error:"+xmldom.parseError.reason);        }    }else{        throw new Error("No XML parser available.");    }    return xmldom;}


When using the above functions, you should capture exceptions.

As follows:

var xmldom = null;try{  xmldom = parseXml("
 ");}catch(ex){  alert(ex.message);}

Serialize XML

function serializeXml(xmldom){  if(typeof XMLSerializer!="undefined"){     return (new XMLSerializer()).serializeToString(xmldom);  }else if(typeof xmldom.xml!="undefined"){     return xmldom.xml;  }else{     throw new Error("Could not serialize XML DOM.");  }}
