NAME

       Parse::MediaWikiDump::Links - Object capable of processing link dump files

ABOUT

       This object is used to access content of the SQL based category dump files by providing an iterative interface for extracting the
       indidivual article links to the same. Objects returned are an instance of Parse::MediaWikiDump::link.

SYNOPSIS

	 $pmwd = Parse::MediaWikiDump->new;
	 $links = $pmwd->links('pagelinks.sql');
	 $links = $pmwd->links(*FILEHANDLE);

	 #print the links between articles
	 while(defined($link = $links->next)) {
	   print 'from ', $link->from, ' to ', $link->namespace, ':', $link->to, "
";
	 }

STATUS

       This software is being RETIRED - MediaWiki::DumpFile is the official successor to Parse::MediaWikiDump and includes a compatibility library
       called MediaWiki::DumpFile::Compat that is 100% API compatible and is a near perfect standin for this module. It is faster in all instances
       where it counts and is actively maintained. Any undocumented deviation of MediaWiki::DumpFile::Compat from Parse::MediaWikiDump is
       considered a bug and will be fixed.

METHODS

       Parse::MediaWikiDump::Links->new
	   Create a new instance of a page links dump file parser

       $links->next
	   Return the next available Parse::MediaWikiDump::link object or undef if there is no more data left

EXAMPLE

   List all links between articles in a friendly way
	 #!/usr/bin/perl

	 use strict;
	 use warnings;

	 use Parse::MediaWikiDump;

	 my $pmwd = Parse::MediaWikiDump->new;
	 my $links = $pmwd->links(shift) or die "must specify a pagelinks dump file";
	 my $dump = $pmwd->pages(shift) or die "must specify an article dump file";
	 my %id_to_namespace;
	 my %id_to_pagename;

	 binmode(STDOUT, ':utf8');

	 #build a map between namespace ids to namespace names
	 foreach (@{$dump->namespaces}) {
	       my $id = $_->[0];
	       my $name = $_->[1];

	       $id_to_namespace{$id} = $name;
	 }

	 #build a map between article ids and article titles
	 while(my $page = $dump->next) {
	       my $id = $page->id;
	       my $title = $page->title;

	       $id_to_pagename{$id} = $title;
	 }

	 $dump = undef; #cleanup since we don't need it anymore

	 while(my $link = $links->next) {
	       my $namespace = $link->namespace;
	       my $from = $link->from;
	       my $to = $link->to;
	       my $namespace_name = $id_to_namespace{$namespace};
	       my $fully_qualified;
	       my $from_name = $id_to_pagename{$from};

	       if ($namespace_name eq '') {
		       #default namespace
		       $fully_qualified = $to;
	       } else {
		       $fully_qualified = "$namespace_name:$to";
	       }

	       print "Article "$from_name" links to "$fully_qualified"
";
	 }
