Hello Marc,
thanks for your hints. No, I can't use the standard pdf serializer,
because I have to create them with a external application.
I tried to get my custom order with a flowscript. But that doesn't
work, too. I can't call another process (start the external app with
my action) _after_ the serialization of the html.
It's frustrating...
Come on Stefan ;)
You can work with a setup very similar to the one I gave recently at [1]
for a completely different use case. In contrary to this example your
setup would be (again 3 pipelines):
// same pattern as before
<map:match pattern="">
// delegate to a flow script function
<map:call function="process"/>
</map:match>
// get file, transform it and write it to disk
<map:match pattern="getFile">
<map:generate/>
// your transforms
<map:transform type="write-source"/>
<map:serialize type="xml"/>
</map:match>
// final processing
<map:match pattern="showHtml">
<map:act type="MyCustomAction"/>
// it's probably possible to inject the document directly,
// otherwise get and transform the file again
<map:generate/>
// your transforms
<map:serialize/>
</map:match>
flow script:
function process() {
var pipelineUtil = // get pipelineUtil
var data = // data you might need to retrieve the file
var document = pipelineUtil.processToDOM("getFile", data);
cocoon.sendPage("showHtml");
}
This is the easiest conversion possible I think. But having this setup
you might improve and simplify it by dropping SourceWriteTransformer and
changing the implementation of MyCustomAction a bit, so that it is no
longer a Cocoon Action and no longer needs to reparse the file from disk.
1. drop <map:transform type="write-source"/> and <map:act
type="MyCustomAction"/> completely
2. flow script:
function process() {
var pipelineUtil = // get pipelineUtil
var data = // data you might need to retrieve the file
var document = pipelineUtil.processToDOM("getFile", data);
var myCustomAction = // get MyCustomAction, either POJO or simple
// component independent from sitemap
myCustomAction.process(document);
cocoon.sendPage("showHtml");
}
You can also store the DOM on the disk to retrieve it from
MyCustomAction. That's still better than to clutter the sitemap.
Furthermore PipelineUtil provides methods to work with DOM, SAX or
OutputStream, so you can integrate them even more, e.g. by providing a
SAX ContentHandler.
Hope that gets you the idea.
