How to display wrongly-formatted XML?

[dcnguyen]

I've got an ajax call that reads a xml response as such:

var xmlDoc = request.responseXML;
var responseNode = xmlDoc.documentElement;
foo(responseNode);


What would I test to see if responseNode was properly formatted XML? Sometimes, the php script will echo an error that's not xml formatted...so I'd like this test to basically output anything that's not proper xml to an alert box.

You use the parseError method in javascript to find out if you have any problems with incoming XML.

The following is a snippet of code I made/copied that tests incoming XML:

  if(xmlDoc.parseError.errorCode!=0) {
     txt="Error Code: " + xmlDoc.parseError.errorCode + "\n";
     txt=txt+"Error Reason: " + xmlDoc.parseError.reason;
     txt=txt+"Error Line: " + objXML.parseError.line;
     alert(txt);
  }
  else {
     alert("No errors found");
  }
