Ok, this modification is a small part of my thesis. The reason why the
modification is needed is that I have in the JSP - or maybe in HTML files -
XML tags from an other namespace. These are some placeholders for dynamic
content I need to insert. A simple example would be:
<div>
<xyz:widget param1="<%= var1%>" param2="<%= var2%>"></widget>
</div>
should be converted to
<div>
<ol>
<li><%= var1%></li>
<li><%= var2%></li>
</ol>
</div>
How to transfer the resource to the needed output format is easy to do for
me but like I told a have no clue how to pass the new resource on the fly to
the server that he could render/compile and deliver it to the client. I also
get to know that my approach is a kind of hacky - but it's not for a live
server - only development. So it's not problem when it's hacky or has a bad
performance. :)

The reason is that it should be possible to modify not only JSP file but
also HTML or declarative documents at all.

Yes your are alright. I explained wrong :) I mean that the document is read
and compiled in one process. I know that it's possible to modify the request
before processing - but I couldn't find a possibility to handle the loaded
resource before compiling.
Thanks for the help,
Martin
