[xsl] RE: Re: How to express a select attr in for-each for conditional or nonconditonal case.

["E100 SFYang" <SFYang@xxxxxxxxxxxxx>]

Hi,  Chris,
Thanks for the good  solution,   I can see your point now;

><xsl:for-each
select="$source[contains($keywrd,.)]|$source[$keywrd='']">

The select attr  is actually expressed from union of two sets,   this is
something I can use from now on.
Just for curiosity, will it cost some speed performance  by going
through two patterns each time?  Or a
better solution for what I want to achieve?
