RE: [xsl] Multiple Grouping & Muenchian Method

["Jacoby, Peter R." <PJACOBY@xxxxxxxxxxxx>]

>>Is it possible to have a group within a group.

Hi, Steve,

You were really close in your code.  The concept that you were missing is to
define one xsl:key with two parameters using the concat function.

If you change your key declaration to be
<xsl:key name="byDateAndCountry" match="entry"
use="concat(parent::group/parent::date/text(), country)" />
or more succinctly:
<xsl:key name="byDateAndCountry" match="entry" use="concat(../../text(),
country)" />

You can then call one key indexed by an entry's date as well as country.

A full stylesheet is below.  Please let us know if you have any other
questions.
This all becomes a lot easier in 2.0 with xsl:for-each-group.  Hopefully
someone
will post the 2.0 solution so we can see how much simpler it is.
