Re: [xsl] multiple input document question

["Greg Fausak" <lgfausak@xxxxxxxxx>]

Michael,

You must be psychic, because that's what I was asking!

For my purposes it would have been more elegant to put
the xpath information in one xml document which points
into another. It's easy enough if you put all of the logic in the
.xsl sheet, which is what I ended up doing.

Thank you,
