What is the best way to parse (get a DOM tree of) a HTML

  • 0

What is the best way to parse (get a DOM tree of) a HTML result of XmlHttpRequest in Firefox?

EDIT:

I do not have the DOM tree, I want to acquire it.

XmlHttpRequest’s “responseXML” works only when the result is actual XML, so I have only responseText to work with.

The innerHTML hack doesn’t seem to work with a complete HTML document (in <html></html>). – turns out it works fine.

    innerHTML should work just fine, e.g.

    // This would be after the Ajax request:
var myHTML = XHR.responseText;
var tempDiv = document.createElement('div');
tempDiv.innerHTML = myHTML.replace(/<script(.|\s)*?\/script>/g, '');

// tempDiv now has a DOM structure:
tempDiv.childNodes;
tempDiv.getElementsByTagName('a'); // etc. etc.
