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( Patterns => $patterns,
					    Matcher => $matcher,
					    File => $file );

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. Patterns is the pattern-action list to apply. Matcher is an instance of the pattern or query matching module. The File option is an open io handle (see IO::Handle) to write to, if the File option is missing, Amsterdam defaults to writing to standard output.

Each action in Amsterdam contains either or both a Before and an After string to copy to the output before and after processing an XML element.
