Question

I am trying to parse a large XML file using JavaScript. Looking online, it seems that the easiest way to start is to use the browser’s DOM parser. This works, and I can get elements by ID. I can also get the “class” attribute for those elements, and it returns what I would expect. However, I don’t appear to be able to get elements by class.

The following was tried in the latest Chrome:

xmlString = '<?xml version="1.0"?>';
xmlString = xmlString + '<example class="test" id="example">content</example>'

parser = new DOMParser();
xmlDoc = parser.parseFromString(xmlString,"text/xml");

xmlDoc.getElementById("example");    
      // returns the example element (good)

xmlDoc.getElementById("example").getAttribute("class");
      // returns "test" (good)

xmlDoc.getElementsByClassName("test");
      // returns [] (bad)

Any ideas?

You can use JQuery to parse an XML file by using a class selector. http://jquery.com
