Can AJAX dealing with XSLT instead DOM?

RC
Let's say:

if (XMLHttpRequest Object.readySta te == 4 &&
XMLHttpRequestO bject.status == 200)
{
// Now I got an XML object here
var xmlDocument = XMLHttpRequestO bject.responseX ML;
// next I have dealing with XML file tags used DOM.
var options = xmlDocument.get ElementsByTagNa meNS(null,"myXM LTag");
doMyFunctionWit hHTMLDOM(option s);
}

The problem is DOM requires you are an excellent JavaScript programmer
to deal with firstChild, lastChild, nextSibling, etc.
And 2nd problem is different browsers will have different results.
Sometime work in Firefox/Netscape, but not work in IE, etc.

In my XML file has a line
<?xml-stylesheet type="text/xsl" href="myXSLTFil e.xsl" ?>

I would like use a very simple XSLT file do the work, no DOM programming
deal with those "children".
So back to my question, How to use AJAX to deal with XSLT instead deal
with DOM?
Thank you very much in advance!

Here is an example of XML and XSLT files, they are working fine.

------------XML----------------------------------------
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<?xml-stylesheet type="text/xsl" href="test1.xsl " ?>

<states>
<state_code>N Y</state_code>
<state_code>N J</state_code>
<state_code>N M</state_code>
<state_code>N C</state_code>
<state_code>N H</state_code>
</states>

------------XSLT-----------------------------------------------
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html" />

<xsl:template match="states">
<form>
<select>
<xsl:apply-templates select="state_c ode" />
</select>
</form>
</xsl:template>

<xsl:template match="state_co de">
<option value="{text()} ">
<xsl:value-of select="text()" />
</option>
</xsl:template>

</xsl:stylesheet>

Your pure (or core) JavaScript skills don't matter much to manipulate
the DOM, you need to know the document object model and the differences
in the browser implementations .
And 2nd problem is different browsers will have different results.

I don't think you gain much by moving to XSLT as you still need script
to run the transformation and as the differences in XSLT processor APIs
are worse than the DOM differences. And finally you need to insert the
result of the XSLT transformation into the HTML DOM document.

Mozilla's XSLT processor API is documented here:
<http://developer.mozil la.org/en/docs/Using_the_Mozil la_JavaScript_i nterface_to_XSL _Transformation s>
Opera 9 supports the same API.

IE 6 and later use MSXML 3 to support XSLT 1.0, there are different APIs
you can use with MSXML (e.g. transformNode, transformNodeTo Object, and
an XSLT processor API to set parameters).

Opera 8 does not support client side XSLT 1.0. Nor do IE 5 and 5.5
unless MSXML 3 is installed in addition to IE.

Safari/Konqueror I think support client-side XSLT but have no API
exposed to JavaScript.

Take a look at the http://jquery.com/ lib. Very handy.

Why not apply the XSLT on the server side before sending it to the client?

That doesn't require extensive Javascript knowledge. It does require
knowledge of the DOM--which isn't more complex than XSLT and XPATH.
Besides that, you have to use Javascript to apply the XSLT
transformation anyway, as well as to accomplish whatever update of the
current page needs to occur after the transformation is complete. *That*
requires you to program with the HTML DOM--and if you know how to do
that, then you pretty much know how to use the pertinent features of the
XML DOM too.
