=head1 NAME

xmlnsnorm - normalises namespace prefixes in XML files

=head1 SYNOPSIS

  xmlnsnorm -m 'URI prefix' [ -m 'URI prefix' ... ] [ <filename> ]

  Options:
   -m <mapping> specify URI to prefix mapping (space separated)
   -h           help - display the full documentation

  Example:
   xmlnsnorm -m 'http://purl.org/dc/elements/1.1/ dc' in.xml >out.xml

=head1 DESCRIPTION

This script takes an XML document either on STDIN or from a named file and
writes a 'normalised' version of the file to STDOUT.  Any prefixed names
(elements or attributes) associated with a mapped namespace URI will have their
prefix changed to the prefix you specify.  Any namespace prefixes which occur
in the document but for which you have not specified a mapping, will be passed
through unchanged.

=head1 SEE ALSO

This script uses the following modules:

  XML::SAX::ParserFactory
  XML::Filter::NSNormalise
  XML::SAX::Writer
