Re: [xsl] what does xsl:sort do if "select" doesn't evaluate to anything?

Hi Robert,

You mean if the result of the select expression is an empty node set?
The empty node set gets turned into an empty string, which will then
be sorted in the same way as any other empty string. Usually in
alphabetical sorting that means such nodes will be sorted before those
whose sort key has some characters in it.

Cheers,

Jeni
