WWW::Wikipedia - Automated interface to the Wikipedia


  use WWW::Wikipedia;
  my $wiki = WWW::Wikipedia->new();

  ## search for 'perl' 
  my $result = $wiki->search( 'perl' );

  ## if the entry has some text print it out
  if ( $result->text() ) { 
      print $result->text();

  ## list any related items we can look up 
  print join( "\n", $result->related() );


WWW::Wikipedia provides an automated interface to the Wikipedia http://www.wikipedia.org, which is a free, collaborative, online encyclopedia. This module allows you to search for a topic and return the resulting entry. It also gives you access to related topics which are also available via the Wikipedia for that entry.


To install this module type the following:

    perl Makefile.PL
    make test
    make install



The constructor. You can pass it a two letter language code, or nothing to let it default to 'en'.

    ## Default: English
    my $wiki = WWW::Wikipedia->new();

    ## use the French wiki instead
    my $wiki = WWW::Wikipedia->new( language => 'fr' );

WWW::Wikipedia is a subclass of LWP::UserAgent. If you would like to have more control over the user agent (control timeouts, proxies ...) you have full access.

    ## set HTTP request timeout
    my $wiki = WWW::Wikipedia->new();
    $wiki->timeout( 2 );

You can turn off the following of wikipedia redirect directives by passing a false value to follow_redirects.

Together with the Wiki markup, some entries include HTML tags. They can be stripped out using the clean_html option:

   my $wiki = WWW::Wikipedia->new( clean_html => 1 );

See clean_html documentation bellow for details.


This allows you to get and set the language you want to use. Two letter language codes should be used. The default is 'en'.

    my $wiki = WWW::Wikipedia->new( language => 'es' );
    # Later on...
    $wiki->language( 'fr' );


Allows to get/set if HTML is being stripped out.

    # set HTML strip
    $wiki->clean_html( 1 );

This option removes all tags and attributes they might have. Their contents, however, is maintained (for now). Comments are also removed.


By default, wikipeda redirect directives are followed. Set this to false to turn that off.

Which performs the search and returns a WWW::Wikipedia::Entry object which you can query further. See WWW::Wikipedia::Entry docs for more info.

    $entry = $wiki->search( 'Perl' );
    print $entry->text();

If there's a problem connecting to Wikipedia, undef will be returned and the error message will be stored in error().


This method fetches a random wikipedia page.


This is a generic error accessor/mutator. You can retrieve any searching error messages here.


  • Be more specific on the HTML clean methodology. For now all tags are removed, keeping only their contents. In the future the behaviour might change accordingly with each specific tag.

  • Watch the development of Special:Export XML formatting, eg: http://en.wikipedia.org/wiki/Special:Export/perl


  • LWP::UserAgent
