[xsl] RE: [SPAM-BA] - Re: [xsl] decorator / wrapper design

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. But in fact I don't now before hand what the elements are that
need italic or bold. So I want to make templates (or something) that
surround some context with some elements. Then I want to call these
templates with a node that is then wrapped.
In a C like programming environment, this is what I want:

function bold(var content) {
  return "<B>"+content+"</B>";
}

function italic(var content) {
  return "<I>"+content+"</I>";
}

print bold(italic(some node));

I hope this is more clear.

greetings and thanks,
Lucas

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 :)
