[Greasemonkey] Re: Greasemoney 0.6.4

You really have three choices:

The easiest way is to just use unsafeWindow.DOMParser:

alert(new unsafeWindow.DOMParser().parseFromString("<foo/>", "text/xml"));

Though, as the name says, unsafeWindow isn't as safe as using normal
Greasemonkey APIs. See
http://greasemonkey.mozdev.org/authoring.html#unsafeWindow for more
information on this to decide whether it's appropriate for you.

You can also use a new XML API which just came out in Firefox 1.5
called E4X. I personally prefer it, but it seems to be stricter than
DOMParser, which caused some people some headaches.

It also doesn't like XML declarations (<?xml version="1.0"?>) so if
the thing you're trying to parse has one, you need to use a regex to
remove it before parsing it. eg:

var foo = new XML(strXMLWithDecl.replace(/<\?xml.*?\?>/g, ""));

You can get more information about e4x here:

http://developer.mozilla.org/en/docs/E4X
http://en.wikipedia.org/wiki/E4X
http://www.linkwerk.com/pub/javascript/e4x/e4x-tester/

Finally, if what you're really trying to parse in XHTML which has some
likelihood of being invalid tag soup, you may want to use this hack
that I demonstrated for someone else:
