Hy,
I need to transform one source into two different views
and finally collect these views into one single output page.
I do this with an aggregation, that implicitly calls the
same source twice and feeds the result into different
transformers:
<map:match pattern="search/canvas">
<map:aggregate element="canvas">
<map:part element = "coll" src="cocoon:/search/coll"/>
<map:part element = "mask" src="cocoon:/search/mask"/>
</map:aggregate>
<map:transform src = "canvas.xsl"/>
<map:serialize type = "html"/>
</map:match>
<map:match pattern="/search/coll">
<map:generate src="http://myserver/collection.xml"/>
<map:transform src="collection.xsl"/>
<map:serialize type = "xml"/>
</map:match>
<map:match pattern="/search/mask">
<map:generate src="http://myserver/collection.xml"/>
<map:transform src="mask.xsl"/>
<map:serialize type = "xml"/>
</map:match>
The goal is to call the http: request only once,
not twice as is done with the sitemap above.
One possible solution would be to create one single
XSL-transform by merging the rules of canvas.xsl
and collection.xsl into one merge.xsl and add a template that
actually controls the merge. That would result in calling
the http only once, but i do not want to solve it like this,
because the only place, where i want to define the merge shall
be the sitemap i.e. within the first match rule above.
Now the question raises, how i can gather an xml-fragment,
put it into some temporary place (ideally in memory) and
refer to this fragement from another part of the pipeline.
On top of this the xml-fragment should be kept local to the
request (each request retrieves the fragment and puts it
into a request-bound place and after the request terminates throw
away the fragment)
any ideas, how this could be achieved ?
regards, hussayn
