Re: how can I do this ? (in C2???)

[fo...@neonics.com]

Hello there,

this example should work fine in C1 but I'm trying to get something
like this working in C2..

Since you sound like an expert (not that I didn't already know what
you explained ;)) could you deliver this stylesheet to me working
under C2? The only difference in your stylesheet compared to mine was the
inclusion of the <xsl:copy/> tag.
