Tilmann,
thanks for the patch Tilmann. However, your patch works only when the XSL transformation is successful. Should the transformation fail along the way then not all 3 DOM trees are there (HTML, RDF and XSL) and thus one or more of the tree delete statements would fail, potentially leaving one or more of the other (valid) trees behind.
I patched irc::logger::apply_xslt accordingly on HEAD. (Isn't that where all new development should go?).

P.S. Could you give me -as the maintainer- a heads up next time you have patches to irc-logger? Thanks.
