Parse::MediaWikiDump::Links(3pm) User Contributed Perl Documentation Parse::MediaWikiDump::Links(3pm) 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
