Ajax with XML and XSL

[bcochofel]

Hi, I want to update part of a XML output (generated by Perl CGI). I'm
using XSL to transform the XML.

Can I use this approach?

I need to resort the contents of a table, that gives me the results
from a query, when someone clicks on one of the names of that table.

Thanks,
Bruno

Several approaches are possible:

- XSL: not my favourite, browser dependencies, client side
- TDC: only for Internet Explorer, handy, quick, propietary, the same
concept as eg VBScript, MS Help Viewer, ActiveX, etc.
- Perl: XML::Simple/XML:arser, server side, low client requirements,
solid
- Ajax: probably okay

I'm working with Linux, so no TDC...
I have to work only on the client side, but without XSL (I don't know
how to use XSL on the client...)
I guess I'll have to stick with Ajax. My problem his: How can I read
the elements from the XML? DOM? Don't know much about DOM.

Can I save the elements (using DOM) to an array in Javascript so them I
can resort whatever I want?

That's what I would have done...

Loop through the DOM to build your JS array, and build your table
from that.
Each time the user clicks on a column heading, resort the array
and rebuild your table from JS.

My problem his that I have to use XSL on the server side to generate
the table.
Maybe after that I can create the JS array but I'll have something like
this (in XML):

<?xml version="1.0" encoding="iso-8859-1"?>
<?xml-stylesheet type="text/xml" href="RR.xsl"?>

So <site> can have several <tag> elements.
How can I create an array with JS like this? I want to sort by
site[@url] attr, tag[@name], or tag[@weight]...
