Hi,
Is it possible to use the tokenize function in an XSL transformed by cocoon? I've had a little play with something like the following transform:
<xsl:stylesheet version="2.0"
xmlns:fn="http://www.w3.org/2004/10/xpath-functions";
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:cinclude="http://apache.org/cocoon/include/1.0";><xsl:param name="url"/>
<xsl:variable name="urlTokens" select="fn:tokenize($url, '/')"/> <!-- the following line is fine --> <xsl:variable name="urlToken1" select="fn:item-at($urlTokens, 1)"/>
<!-- Something like this line fails with "Unknown error in XPath" --> <xsl:value-of select="$urlToken1" />
<!-- Something like this line fails with an NPE --> xsl:value-of select="fn:item-at($urlTokens, 0)" />
Would Saxon work here?
Would JX be my friend by allowing me to call a StringTokenizer?
I've not really used the JX stuff, and not sure what it's advantages are over XSL when working directly with an XML backend.
How else do you suggest I do this?
I could pass the parameters is from the sitemap, tokenising there with the matcher, but it would mean creating multiple match sections for each level. I might have to do that if there's nothing "neater".
To take a step back, I'm trying to create a trail (breadcrumbs, etc), I had look previously for examples, as I seem to recall seeing one, but couldn't find anything.
Given a URI like: http://www.host.com/1/2/3.x or just http://www.host.com/1.x
I'd like a trail that looks like:
1 -> 2 -> 3 with links to 1.x, 2.x, 3.x or 1 with a link to 1.x
Well, I can sort out all the rendering, I just don't know how to tokenize the URI I'm passing in. Or am I approaching it wrong?
Thanks for your time, Ben Pope.
