Re: [xsl] Getting a predicate right

[Joerg Heinicke <joerg dot heinicke at gmx dot de>]

Hello Matt,

with this description only the question of the context remains. If a 
<mesg> element is the context element, your XPath expression should be

<xsl:value-of select="/test/colors/desc[@id = current()/@grp]/@name"/>

I assume this is what you want.

"desc[@id = @grp]" can not work because both attributes refer to the 
<desc> element, which means the XPath is only true for a <desc> element, 
whose value of @id is the same like the value of @group.

Regards,

Joerg
