I prefer we have a servlet that generates only XML, and then generate HTML from this XML. Do you dislike that approach for some reason?

I am working on "XSLT result" now, it seems easy.
OpenSearchServlet will return xml result by default, and xslt result
by "format=xslt", also you can config xslt location. Anyone need
velocity/freemaker result?
Thanks

So the idea is that the "format=" supplies the name of the stylesheet?
That sounds good to me. Any objections?

Done.

Are you interested in contributing the server-side XSLT solution? I
have no immediate plans to implement that.
Cheers,
Doug

you mean by src/java/org/apache/nutch/searcher/OpenSearchServlet.java ?
Sorry, didn't realize that you have done this already (whereas Eric said
mentioned
something like this on the Lucene mailing list)
I think it would make sense to add <?xml-stylesheet, because XML parsers
won't mind,
but it allows client side rendering by XSLT such as for instance
http://search.msn.ch/results.aspx?q=Nutch&format=rss&FORM=ZZRE
Also I think it would make sense to put a link within the search.jsp to
the OpenSearchServlet

yes, that would be the idea that people can tweak it. Also the XSLT file
name
could be made configurable within web.xml

yes, but I think it might make sense to "hardcode" this because of
performance issues, because XSLT transformations (depending on the XSLT)
can drag down the server
(of course one could cache the XSLT within memory, but nevertheless ...)

to add it as another example as well would certainly make sense.
Just let me know if I can help on any of these issues or if you or anyone
else has already started.

That's currently implemented, without the <?xml-stylesheet.

This we need to add. Most users of Nutch will probably tweak it, but a
good example would be nice to have in SVN.
> 3) div-like HTML with a CSS
This could also be generated server-side with XSLT, from the same XML,
no? It's just another example, right?

(sorry for posting directly into the mailing list, but the httpd in
front of Jira
returns a Bad Gateway currently. I will repost this later.)
no, not at all. I much more prefer a servlet. I have a servlet which I
use for a meta search engine and could change it for the purposes of Nutch.
It currently offers the following three variations:
1) "pure" XML (plus <?xml-stylesheet ... which might be executed on the
client side)
2) HTML, but which is generated out of the XML based on a server side XSLT
3) div-like HTML with a CSS
Would that make sense?
