== Database driven website with Cocoon ==

Hi all,

I went trough Leigh Dodds’ “Database driven website” tutorial (very
interesting) and I have now a question on a slightly different architecture:

My content is NOT stored within a database – Only the PATHs to the content
is stored therein –
I cannot figure out (and this for a couple of weeks now) how to build a
transformers chain for them to to lookup for the PATH of the XML docs
(document content) and of the XSL (styles to be applied to the different
contents) within the database and then fetch both files on the filesystem
for then generate the final HTML document from this.

Any opinion welcome !

Thanks

InputModule-substitution is not needed because the result will be
placed in sitemap parameters anyway.

So, this boils down to: Use anyone of the DatabaseSelectActions and
use the returned sitemap parameter for your path.

So, off my head:

<map:match pattern="*">
  <map:act type="findPath">
     <map:generate src="{documents.path[0]}"/>
     <map:serialize/>
  </map:act>
  <map:redirect-to uri="file-not-found"/>
</map:match>

given that everything is setup properly before.

	Chris.

This first idea (which is not always the best) that comes to mind
would be to retrieve the path e.g. using esql and use the
util:include-uri or friends to include the document.

Another one would be to retrieve the path using one of the
DatabaseSelectActions and use the InputModule-substitution in sitemap
to read that file. (available in 2.1 (cvs) for interpreted sitemap and
2.0.4 (cvs) for compiled sitemap)

Jerome,

Here a suggestion without knowing Leigh Dodds' tutorial ...

I would write an action that puts the path as a variable into the sitemap.

<map:pipeline>
	<map:match pattern="blabla">
		<map:act type="your-action">
			<map:generate src="{your-path}"/>
			...
			<map:serialize/>
		</map:act>
	</map:match>
</map:pipeline>

Your action has to return a map with the key "your-path" and the value.

Regards,
Reinhard
