Hello again Lucas, I understand your needs, you want to apply mutliple tags, in which case, have a look at the link I provided. Right down at the bottom is XSLT 1.0 code, which is probably what you want. I gave you my (*knowingly broken*) stylesheet to try and illustrate that (as is my understanding) a template will applied based on how exact a match is. Chaining the templates is usually fraught with, well, rather ... 'ugly' code. At least to my eye's (and this from a perl programmer ;) regards Stef On Fri, Mar 18, 2005 at 04:08:47PM +0100, Schaik, L.B. van wrote: > Hi, > > Thanks Stef for this solution, but what I want is a little different: > In the example, it is clear that I want title and paragraph formatted > this way.
