XSLT sorting

[bcochofel]

I'm using xsl to list an xml file that contains something like: sites,
tag and weight.

I'm listing this in a table with the following titles: | URL | TAG |
WEIGHT (each title his a link)

What I want is when someone clicks a title chooses the sorting option,
if this is the actual sorting option then reverses the order. Can I do
this? How?

Here's an example:

---------------------------------------------------------------------------------
    <sites>
    <!--
	  Site url: required (pattern: (https?|ftp)://.+)
	  Tag name: required
	  Tag weight: integer optional
    -->
      <site url="http://www.google.com">
        <tag name="pesquisa" weight="30" />
        <tag name="procura" weight="30" />
      </site>
      <site url="http://www.google.com/webhp?complete=1">
        <tag name="ajax" weight="25" />
        <tag name="pesquisa" weight="30" />
        <tag name="procura" weight="30" />
      </site>
      <site url="https://webmail.fe.up.pt">
        <tag name="email" weight="20" />
        <tag name="feup" weight="20" />
      </site>
    </sites>

Your XSLT probably creates a HTML table. To sort that table you can use
client-side script (JavaScript) if available. You can also use
client-side XSLT to sort if available although then you have to use
script too to run the transformation. A robust solution that works
independent of the browsers XSLT and script support will need to sort
the table server-side meaning a click on that table header will send a
request to the server to do the sorting and send a new document with a
sorted table back.

Well, I'm using Perl CGI to generate the XML on the server-side. On the
XML I have the query params from the script, so I was wondering if I
can use this params to sort within the XSL?
Also, I can I create an url with the value of some elements from my
XML?
Something like (on my xsl file), <a href="listsites.cgi?field=<xml
element value here>&sort=<xml element value here>">sites</a>...

Do you run the XSLT transformation on the server with Perl too? Or do
you rely on the browser doing the XSLT transformation?

element value here>&sort=<xml element value here>">sites</a>...

Use attribute value templates e.g.
<a href="listsites.cgi?field={element-name}&amp;sort={element2-name}">
or xsl:attribute
<xsl:element name="a">
<xsl:attribute name="href">
<xsl:value-of select="concat('listsites.cgi?field=', element-name,
'&amp;sort=', element2-name)"/>
</xsl:attribute>
</xsl:element>

I'm using HTML::Template to generate my XML file (template.xml) Under
that template I have a reference for a local XSL. This is the only way
I know... I'm new to XML...

I don't use Perl, you will have to ask in a Perl group or wait whether
someone here comes along that can help with that Perl package.

It's the same as having a XML file and ref to a local XSL.
The Perl package creates the XML file and on the browser apears the
context...
If I don't put the line: <?xml-stylesheet type="text/xml"
href="RR.xsl"?>
I get pure XML on the browser.
