how to parse xml from javascript string?

[aaronwmail-usenet]

Ok, I've seen many examples of javascript
parsing an XML document retrieved from a file
indicated by a URL.

The problem is I need to parse (usually small)
xml *strings* embedded in the javascript program
or generated locally, and I can't find any way
to do this exposed (even though some internal
part of the engine clearly is capable of doing it).
Am I missing something?

I'm aquainted with Xparse, but it seems to do
strange things with invalid XML
(rather than giving up with an error) and also may
have licensing issues for my purposes. I've seen
references to other parsers implemented in
javascript. Is there a good one with a BSD style
license? Other options?

Please inform! thanks! -- Aaron Watters

The JavaScript engine is capable of parsing XML? Well, yes, the
Spidermonkey engine in Firefox 1.5 can do that but that does not help
currently on the web.
Usually you need a host object for that, Mozilla exposes DOMParser e.g.
var domParser = new DOMParser();
var xmlDocument = domParser.parse FromString(
stringWithXMLMa rkupHere,
'application/xml'
);
Opera 8 also supports DOMParser and has some minimal support for W3C DOM
Level 3 Load and Save too.
I think Safari 2 or at least the latest 2.something release also
supports DOMParser.
With IE/Win for XML you need to use MSXML anyway and there DOMDocument
exposes a method named loadXML to parse a string and create an XML DOM
document.

For older Safari (and probably Konqueror too) people have managed to
parse XML strings by passing the XML markup in a data URL to
XMLHttpRequest, see <http://web-graphics.com/mtarchive/001606.php>

Thanks very much!

Why is it that my 4 recent large books on javascript don't
have this kind of information? Where is an authoritative
reference (online or otherwise) where I can find this kind
of info? Thanks again!

Either bad books, or books describing only the language.
DOM parsers are not part of that, but part of the AOM/DOM.
