Hi,

Sorry if this has been asked before - or is a daft question.

It's a FAQ.
 
Is it possible to parameterise an <xsl:sort> ?

Example.

    <root>
            <data>
                    <firstname value="Fred"/>
                    <lastname value="Smith"/>
            </data>
            <data>
                    <firstname value="Tom"/>
                    <lastname value="Jones"/>
            </data>
            <data>
                    <firstname value="Myles"/>
                    <lastname value="Ward"/>
            </data>
            ...
    </root>

Sometimes I want to sort <data> on "firstname/@value" sometimes on 
"lastname/@value" based on a user parameter of some kind.

Use a sort rule

  <xsl:sort select="*[name() = $x]/@value"/>

where $x is bound to either "firstname" or "lastname".

Cheers,
