Default Using string parameter as an XPath

I need to be able to use my parameter to specify an XPath in one of my templates.


sample input: //boxes

<xsl:param name="inPath"/>

<xsl:template match="$inPath">
..........other code........

How do I convert my string input into an XPath for that kind of use. Right now it just gives me an error.

There is no facility in standard XSLT to do this.

You could do something like <xsl:template match="*[name()=$inPath"> if $inPath was 'boxes'.

What kind of processor are you running your XSLT and at what version ?

If you're running Saxon, you could make use of the "Extension Functions".

Between the following:

You should be able to manipulate an incoming string appropriately to use as an XPath. For full documentation on these functions see the official site.

Im' not as familiar with the other processors available and specific functions they may have, but their may be something similar.

I am using the Saxon processor and the function you provided did the trick! Thanks!
