I don't know, I didn't invest a lot of time in profiling, maybe it  
can be improved.

But if you want an unscientific benchmark here you have :

I compare the two programs xmllint (which comes on my system) and  
xmltrip (compiled without any special option) respectively  
distributed with libxml and xmlm. Note xmllint is a C program so we  
are not comparing to libxml's ocaml interface. Besides I have no idea  
how xmllint is written and what it does internally, maybe it does  
more than xmlm does, so we may well be comparing the uncomparable.  
The files are <http://www.ximpleware.com/xmls.zip>, uncompressed this  
is 144 mb of xml files.

On macos 10.4.8, G4 1Ghz, 512mo ram.

Parse only, without building the tree.

Parse only, building an in-memory tree.
