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.
