Cocoon pipelines in Sling, using XPL - thanks Juanjo! (was: Sling

Great, thanks!
I made minor improvements to error reporting (SLING-908), below are
some notes about how to use this - we'll need to turn this (or better
examples) into some docs later on. For now, just saving this here.
Cool stuff!
-Bertrand
Example using the xproc script engine - rough notes:
1) Install the org.apache.sling.scripting.xproc bundle (found in
contrib/scripting/xproc)
2) Create some content:
$ curl -F sling:resourceType=xproc -F title="some title" -F text="And
some text" http://admin:admin@localhost:8888/foo
3) Create a pipeline script at /apps/xproc/xproc.xpl:
<?xml version="1.0" encoding="UTF-8"?>
<p:pipeline xmlns:p="http://www.w3.org/ns/xproc">
<p:xslt>
<p:input port="stylesheet">
<p:document href="/apps/xproc/one.xsl"/>
</p:input>
</p:xslt>
<p:xslt>
<p:input port="stylesheet">
<p:document href="/apps/xproc/two.xsl"/>
</p:input>
</p:xslt>
</p:pipeline>
4) Store the XSLT transforms in the repository:
/apps/xproc/one.xsl:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:template match="/">
<one>
<xsl:copy-of select="."/>
</one>
</xsl:template>
</xsl:stylesheet>
/apps/xproc/two.xsl:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:template match="/">
<two>
<xsl:copy-of select="."/>
</two>
</xsl:template>
</xsl:stylesheet>
5) Request foo.html to execute the pipeline:
$ curl http://admin:admin@localhost:8888/foo.html
<?xml version="1.0" encoding="UTF-8"?>
<two>
<one>
<foo ...sling:resourceType="xproc" text="And some text" title="some title"/>
</one>
</two>

Thanks Felix. I´ll work at it soon.

Thanks! Just added a note that the xproc module uses the Cocoon 3
pipeline engine.

I have created a documentation page at [1] which should shortly appear
on our site (follow Development -> Integrating Scripting Languages ->
XSLT ...)
This page may be edited directly in the SLINGxSITE wiki to update the site.

Sure, "html.xpl" is fine too.

Of course, should have seen that, but it supports extentions and methods as
well, right?

Hi,

Yeap, XST is still the best option in a lot of situations.

Because of resource type is "xproc", you have:
/apps
+-- xproc [resource type in our case]
-- xproc.xpl [xpl -> script manager is XProc & xproc -> is
not an extesion, so relies on default, i.e. "html"]
Hope this helps,
Juanjo.

Exciting stuff for an old xslt head like myself. Just wondering, if the xpl
file is at /apps/xproc/xproc.xpl, what tells sling that it should resolve
the .html extension in this example to the script?
I would have guessed /apps/xproc/sling/servlet/default/html.xpl ..

It would be cool to explain to the Cocoon community what you've done,
and maybe some parts could be of general interest and could move
there?
Ideally, describing what you've done on the wiki in terms of how the
Cocoon stuff is used would help.
I could do that, but you probably know better - or feel free to point
me to existing info. I've been more or less out of touch with Sling in
the last few weeks, might have missed something.

Cool sample. I hope to have samples and more improvements soon.
