Getting XML snippets using XPATH Javascript

Question

Is it possible to get XML snippets using XPATH in javascript (evaluate function, Chrome)?

How to do it?

Keep getting errors in every approach I've used.

Can you tell us in which enviroment you want to use Javascript and XPath? As you mention evaluate, for Mozilla browsers see developer.mozilla.org/en-US/docs/… and developer.mozilla.org/en-US/docs/Web/API/document.evaluate and post details of code used and errors you get in case the documentation does not help. — Martin Honnen

Here is an example:

var xmlDoc = new DOMParser().parseFromString('<root><foo bar="baz">whatever</foo></root>', 'application/xml');
var xpathResult = xmlDoc.evaluate('//foo[@bar = "baz"]', xmlDoc, null, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null);
while ((el = xpathResult.iterateNext()) != null) {
  alert(el.textContent);
}

Works fine for me with Firefox and Chrome.
