使用XPATH Javascript获取XML代码段

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.

Answer 1

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.
