README  view on Meta::CPAN

The README is used to introduce the module and provide instructions on
how to install the module, any machine dependencies it may have (for
example C compilers and installed libraries) and any other information
that should be provided before the module is installed.

A README file is required for CPAN modules since CPAN extracts the
README file from a module distribution so that people browsing the
archive can use it get an idea of the modules uses. It is usually a
good idea to provide version information here so that people can
decide whether fixes for the module are worth downloading.

  xpath_filter_init($f, $xpath, $namespaces, &transform);

To create a streaming xpath filter this function needs to be called
from filter init. The return value is suitable for returning it from 
filter init.

Every time $xpath matches &transform is called with the subtrees root
node as a parameter.  The namespaces needed to compile the pattern 
are passed as a list [URI, prefix, ...]. Be aware that these prefixes 
are just aliases for pattern usage. They do not need to coincide with 
the prefixes in the document.

  xpath_filter($f, $bb);

This is simply the work horse filter function.
