Re: [xsl] decorator / wrapper design pattern

Hello Lucas,
	It sounds (to me at least) very much like you want
to apply mutliple tags via XSLT. There is a really great
write-up of how someone solved this on the following link;

	http://www.dpawson.co.uk/xsl/sect2/multitags.html

	Its a lot more in-depth than any solution I could
give, and infact, I merely (when I need to do this) exactly
specify something like;

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  version="1.0">

<xsl:template match="/">
        <xsl:apply-templates />
</xsl:template>

<xsl:template match="title|paragraph">
  <i><xsl:apply-templates /></i>
</xsl:template>

<xsl:template match="title">
  <i><b><xsl:apply-templates /></b></i>
</xsl:template>

</xsl:stylesheet>


	use that and you should get a hint as to how apply-templates
works on matches ;>

	regards
	Stef
(ps. I am still learning this crazy thing called XSLT,
so any mistakes, feel free to scream and point :)
