RE: [Babeldoc-devel] DomifyPipelineStage

[Leech, J. <jl...@vi...>]

I'm going to add preemptive caching of DOM representations out of the
XpathSplitter, then I'll commit it all.  That way when an XpathSplitter is
run on a document, it will only get parsed once, and all the sub-documents
will already be parsed.  I'll also look into precompiling XPath expressions.

Jonathan.

Excellent.  Both of these sound GREAT!  I especially like the weakhashmap - 
this really solves this problem elegantly.  Please commit.

Regards,
Bruce.
