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.
