Re: [xsl] can the Muenchian method do this?

[Geert Josten <Geert.Josten@xxxxxxxxxxx>]

Hi,

I think the solution is fine, but that the line:

	<xsl:apply-templates select="/songlist/song[Genre = 'Rap'][Artist !=
preceding-sibling::song/Artist]"/>

should have been:

	<xsl:apply-templates select="/songlist/song[Genre = 'Rap'][not(Artist =
preceding-sibling::song/Artist)]"/>

Regards,
Geert
