Subject Re: (Easy) Passing a Variable From Sitemap to StyleSheet?
Date Wed, 14 Apr 2004 06:31:04 GMT
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 type="cinclude"/>

So set the parameter in the correct tags before calling the include

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 type="cinclude"/>

with in myfile.xml:

<bodytag xmlns:jx="">
    anything you like....



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
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:

    <map:match pattern="ReadMyFile/*.xml">
        <map:generate src="{1}.xml"/>
        <map:serialize type="xml"/>

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,
