RE: XPath transformer?
Jeff, it came up to my mind just now... why don't you use a Xalan extension ? There is an evaluate function in there for such cases. Though I never use it, it seems to fit the bill: see for youself at http://xml.apache.org/xalan-j/extensionslib.html#evaluate .

RE: XPath transformer?
Jeff,
you need just an XSLT transformer for this purpose: use a stylesheet that matches the
wanted element and discards the rest.

Subject: XPath transformer?
Hi,
I have a user manual in XML format:
document
body
s1 title=Introduction
...
/s1
s1 title=Getting Started
...
/s1
...
/body
/document
Is there any way that I could extract out just one s1 element, and
render it as a page? Ie, like an XPath transformer, that would extract a
single node:
map:match pattern=manual/*
map:generate src=manual.xml/
map:transform type=xpath select=/document/s1[@title='{1}']/
map:transform src=chapter2html.xsl/
/map:match
I could then link to chapters with link
href=manual/Introductionintroduction/link.
Is this possible, or should I write my own transformer?
thanks,
--Jeff

RE: XPath transformer?
What you are trying to do can just as easily be achieved with xslt, can't
it?
If you *really* want xpath, you can always write a small xsp-page that
generates an xinclude-statement and then run it through the
xinclude-transformer (which, IIRC will be merged with the cinclude
transformer into a single 'include'-transformer in the near future).

If you need a pagination based on section elements then it's worth to take a
look at Stefano's PaginatingTransformer. You'll find documentation on it
here: http://xml.apache.org/cocoon/howto/howto-paginator-transformer.html.
Hope it'll help you to solve your problem and also hope to see it applied to
Forrest.

Not easily, because the 'match' attribute cannot be dynamic. Eg, I
couldn't do:
xsl:param name=xpath-expr/
xsl:template match=$xpath-expr

AFAIK this is for the same reason that Cocoon doesn't currently have an
XPath matcher.
