Hi Christoph,

I wasn't completely sure how anakia might help with on-the-fly xml
manipulation/presentation, as it seems to be closely tied to ant -
unless you mean running ant on the fly?

er, maybe.  I took a brief look at the source code.  Do you mean
permanently replacing dom4j with dom in the code, or altering code so
that there could be a choice of models?

cheers,

Andy
