NAME
       XML::PatAct::Amsterdam - An action module for simplistic style-sheets

SYNOPSIS
        use XML::PatAct::Amsterdam;

        my $patterns = [ PATTERN => { Before => 'before',
                                      After => 'after' },
                         ... ];

        my $matcher = XML::PatAct::Amsterdam->new( I<OPTIONS> );

DESCRIPTION
       XML::PatAct::Amsterdam is a PerlSAX handler for applying pattern-action
       lists to XML parses or trees.  XML::PatAct::Amsterdam applies a very
       simple style sheet to an instance and outputs the result.  Amsterdam
       gets it's name from the Amsterdam SGML Parser (ASP) which inspired this
       module.

       CAUTION: Amsterdam is a very simple style module, you will run into
       it's limitations quickly with even moderately complex XML instances, be
       aware of and prepared to switch to more complete style modules.

       New XML::PatAct::Amsterdam instances are creating by calling `new()'.
       Parameters can be passed as a list of key, value pairs or a hash.  A
       Patterns and Matcher options are required.  The following OPTIONS are
       supported:

       Patterns
           The pattern-action list to apply.  The list is an anonymous array
           of pattern, action pairs.  Each action in the list contains either
           or both a Before and an After string to copy to the output before
           and after processing an XML element.  The Before and After strings
           may contain attribute names enclosed in square brackets (`"["' NAME
           `"]"'), these are replaced with the value of the attribute with
           that name.  The special NAME `"_element"' will be replaced with the
           element's name.

       Matcher
           An instance of the pattern or query matching module.

       Output
           An IO::Handle or one of it's subclasses (such as IO::File), if this
           parameter is not present and the AsString option is not used, the
           module will write to standard output.

       AsString
           Return the generated output as a string from the `"parse()"' method
           of the PerlSAX event generator.
