Re: (Easy) Passing a Variable From Sitemap to StyleSheet?
I think you're missing the concept of the cinclude. That transformer will
include, yes that's what you need, but it doesn't do anything more than
that. If you need parameter substitution (eg passing a parameter from
sitemap to your document,session/request parameters,...) you'll need to use
another component that does this. One way is to use another transformer, for
example the XSLT transformer:
map:generate src=../
map:transform src=settheparamstylesheet.xslt
map:param name= value=/
/map:transform/
map:transform type=cinclude/
So set the parameter in the correct tags before calling the include
transformer.
This isn't exactly a good way to do that (well in my eyes of course, if you
only want an xml with an inclusion of a particular file:), I would use a
JXTemplateGenerator (docs in your distrubution under user docs/flow).With
this generator you'll have access to variables such as the sitemap, request
and session parameters, use this as follows:
map:generate type=jx src=myfile.xml
map:param name=myparam value=myvalue/
/map:transform/
map:transform type=cinclude/
with in myfile.xml:
bodytag xmlns:jx=http://apache.org/cocoon/templates/jx/1.0;
anything you like
cinclude:include
src=cocoon:/ReadMyFile/${cocoon.parameters.myparam}.xml/
/bodytag
The cocoon:/ is just your protocol you want to use (here it will go through
your current sitemap for a match)
The 'ReadMyFile/' is a uri part to identify a pipeline (see further)
The ${cocoon.parameters.myparam} is one way to access your 'myparam'
parameter passed from your sitemap with the help of the
JXTemplateGenerator.(here using jexl, you may also use jxpath)
Thus when generating your document, the parameter will be filled in by
JXTemplateGenerator and afterwards cinclude will have the correct value to
use.
Remember that if you want to read another file into that location (as in
this example) you'll need another pipeline that matches that file and just
reads in and serializes the content:
eg:
map:match pattern=ReadMyFile/*.xml
map:generate src={1}.xml/
map:serialize type=xml/
/map:match
This just reads your file (you may want to do more with that file if you
like, eg another include or styling...) and the include transformer places
the outcome of the pipeline at the cinclude:.. tag.
(The latter way is not the only way, but seems, in this case, the more
appropriate one to me)
Hope this helps,
Kind Regards,
Jan

Re: (Easy) Passing a Variable From Sitemap to StyleSheet?
Just one other thing (I kinda forgot this;):
You keep mentioning XSLT, but never really used it? Your pipeline was:
map:match pattern=cinc2/*.html
map:generate src=cinc2/template.xml/
map:transform type=cinclude
map:parameter name=requestedfile value={1}/
/map:transform
Here you're reading a file as XML and directly use your cinclude
transformer. Hence no XSLT transformer ever comes in the picture!
Keep in mind that if you want to use XSLT , use the transformer to do this,
if you only inteded to read a file and transform it you might want to use
this:
map:generate src={1}.xml/
map:transform src=mystyle.xsl/
map:serialize/
The default transformer (normally this would be the XSLT, if not, use
type=xslt, or the name used in defining that transformer, above in your
main sitemap) will be used on your file that will only be known at runtime.
Kind Regards,
Jan

You can't do it directly within the document. But maybe you just need to
think about the problem a little differently. Remember you don't need this
aggregate document to physically exist. It just needs to be assembled at
some point in your pipeline.
So I'd use a stylesheet to get what you. Often you can structure your
stylesheet(s) as a general template into which you pass params to
configure
the included subelements. So you might have a simple document (say a table
layout template for your page) and use the pipeline to pass the
configuration information to the stylesheet that modifies your basic
document. I do this with a single style sheet into which I pass params to
cinclude the various fixed and variable content of each page's layout.
HTH,

RE: (Easy) Passing a Variable From Sitemap to StyleSheet?
I posted earlier this week about needing to pass a variable from the
sitemap to a stylesheet, and I understand how to do this, but I'm
getting a weird error now. [NOT SURE HOW TO ESCAPE HTML FOR POSTS TO
MAILING LIST.]
I'm setting the variable in the sitemap as follows:
map:match pattern=cinc2/*.html
map:generate src=cinc2/template.xml/
map:transform type=cinclude
map:parameter name=requestedfile value={1}/
/map:transform
...
My file template.xml WORKS when hard-coded (cheating) with a filename,
as follows:
...
thebody
cinclude:include src=cinc2/mybody.xml/
/thebody
...
but in reality I need the filename parameterized as follows:
...
xsl:param name=requestedfile/
...
thebody
cinclude:includexsl:attribute name=srcxsl:value-of
select=$requestedfile//xsl:attribute/cinclude:include
/thebody
...
This throws an error as follows:
org.apache.cocoon.ProcessingException: Failed to execute pipeline.:
org.xml.sax.SAXException: Missing 'src' attribute on cinclude:include
element
I can't even get this to work, as a test, where I hard-code the
attribute value:
thebody
cinclude:includexsl:attribute
name=srccinc2/mybody.xml/xsl:attribute/cinclude:include
/thebody
Thanks for any assistance.

RE: (Easy) Passing a Variable From Sitemap to StyleSheet? - One complication
Hi David. This is more of an XSLT question now really, if I understand you
correctly.
You should use attribute value templates (i.e. curly braces):
xsl:variable name=foo/
...
cinclude:include src={$foo}/
You could indeed use xsl:value-of, like this:
cinclude:include
xsl:attribute name=src
xsl:value-of select=$foo/
/xsl:attribute
/cinclude:include
... which is a bit wordy. The attribute value template approach above is
functionally identical - it's just a handy shorthand syntax.
Cheers
