Dynamic sorting of elements

[chantey]

Hi guys,

Im still fairly new to XML and need help on the following problem.

I know how to sort elements alphabetically using my XSL stylesheet. All I do is use <xsl:sort> in the template.

I want some buttons or links on my XML page that will dynamically change the sort order.

For example, if i have the following data

Book A (2004)
Book B (2002)

Given by

<books>
<title>Book A
<year>2004</year>
</title>
<title>Book B
<year>2002</year></title>
</books>

I want a button that says 'sort by title' which when clicked, will sort the list by title, and a button that says 'sort by year' which when clicked, orders the list by year.

Is this possible?
Any help would be appreciated.

Thanks

It is possible: you can put <xslaram name ="sortfield"/>
in your stylesheet, and use it in <xsl:sort select="*[name()=$sortfield]"/>
How you pass parameters to your XSLprocessor depend a bit on the situation.
However, this way you parse the whole page again.
I can imagine someone invented a trick do do sorting in javascript, so without parsing the whole page again, - but I wouldn't know how...

For those interested:
of course it is possible to change the sort-order using java-script, and of course MS documented it:
