Translating XML from memory instead of disk

[Bert Van Kets <be...@visitronics.be>]

Hi Cocooners,
I'd like to create an HTML report from data stored in a database.
If I create an XML document in memory, how do I go about having it 
translated with Cocoon2 to my HTML report?
Do I need to create a generator, or can I just add something to the sitemap 
so that the source for the XML is not a file, but an object in memory?  Do 
I need to use a SAX parser or can I use a DOM parser too?
Can anybody direct me in the right direction please?
Thanks,
Bert

Since your requirement is only "create an HTML report from data stored in a database" I guess I'd suggest not creating an XML document in memory as that can be a bit of a space hog and inefficient.  I'd prefer sticking with the SAX model that C2 uses.

So in that spirit, I'd recommend this:

1) either:
         * Write an XSP page (which is a generator) with esql tags in it to read from the database and then generate whatever xml output you need

         or

         * Write an XML document with a sql query in it and then run the SQL transformer against it to read from the database

2) run a stylesheet on the results to transform the xml into html

3) serialize as HTML


If you do absolutely have to create an XML document in memory, that can be dealt with too.  You can write an XSP page to handle writing XML documents/fragments to the Cocoon pipeline.

If I haven't answered your question well, then please clarify a bit more what you're looking for.
