Re: [xsl] Muenchian grouping: help with 'use' and multiple elements

[Mukul Gandhi <mukul_gandhi@xxxxxxxxx>]

Hi Justin,
Please just modify the 1st line of stylesheet with -

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xalan="http://xml.apache.org/xalan";
exclude-result-prefixes="xalan">

This will cause
xmlns:xalan="http://xml.apache.org/xalan"; not to be
generated in the output.

Regards,
Mukul
