SYNOPSIS

package foo;
use Meta::Xml::Parsers::Collector qw();
my($parser)=Meta::Xml::Parsers::Collector->new();
$parser->parsefile($file);

DESCRIPTION

The orignal XML::Parser gives you character information bit by bit and there is no way to tell it to give you the whole content at a single instant. This parser is defined to make life easier for you to do that. All you need to do is: 1. inherit from this parser instead of XML::Parser. 2. override the handle_endchar method (just like any other handler override for XML::Parser) and the element you get there is the entire content.

A default handler for endchar is installed with this parser and does nothing.

Be aware that by inheriting from this parser you are assuming that all the char data in your XML files is small enough to fit easily in RAM. The XML::Parser is designed to do it's stuff the way it is for a reason (parsing xml files with very large binary data in them etc...). If this is your need you better use the original XML::Parser.

I do intend to make some extensions for this parser whereby you could say which elements you want to handle piece by piece and which it can just gallop down but this is currently unimplemented.

Take care to either not to override the handle_char method or to call your super class implementation of it because this parser does stuff in there too.

You don't HAVE to overrider the handle_endchar method. You can write your parser and grow with it. When you need it it will be there for you.

FUNCTIONS

new($)
handle_start($$)
handle_end($$)
handle_char($$)
handle_endchar($$$)
TEST($)

FUNCTION DOCUMENTATION

new($)

This gives you a new parser object.

handle_start($$)

This will handle start tags. Currently it just null the string collected.

handle_end($$)

This will handle end tags. This handler actually calls the handle_endchar which you have overriden (hopefully).

handle_char($$)

This will handle actual text. This accumulates the snipplet given to it by XML::Parser into the string.

handle_endchar($$$)

This is the handle you need to override to get the entire element. In this parser this does nothing.

TEST($)

Test suite for this module.
