Richard,

The best way to achieve this is to have a good XSLT Debugger.

With the Xselerator, I place a breakpoint at the line with the "xsl:message"

and when/if the Debugger stops at that breakpoint, I simply watch the "Call stack"
window.

Without a debugger you cannot achive this without significantly changing you code --
sometimes this can be very difficult!

Cheers,
