Compilation instruction:

compile the TextCollection :

cd XMLTree/TextCollection
make

compile libcds :

cd XMLTree/libcds
make

compile XMLTree :
cd XMLTree
make

compile xpathcomp/
make


Building xpathcomp requires:

libxml2.6++-dev 
ocaml-findlib
ocaml-ulex
ocaml-nox
camlp4

and their dependencies


you can compile with make DEBUG=true to get more statistics the overall programm is slower
but you get precise timing for each individual function calls to the XMLTree interface.


Usage :
./main 'file.xml' 'query' [output]

file.xml is the input file. There are some in the tests subdirectory. At the moment you can mainly test
with base.xml and tiny.xml. Any file bigger than this will take too much time to load.
If the file ends with the .srx extensions then it is considered to be a serialized output saved to disk
with the -s flag (see bellow).


output is optional. If specified, it is the name of a file to which the result of the query is serialized.
If output is not given, the the result of the query is kept as a set of identifier and no access to
the string collection is made.




There are a few flags:

./main <input.{xml|srx}> 'query' [output]

  -c counting only (don't materialize the result set)
  -max-tc set maximum count for which the TextCollection is used
  -f sample factor [default=64]
  -s save the intermediate representation into file.srx
  -b real bottom up run
  -help  Display this list of options
  --help  Display this list of options
