Parse::MediaWikiDump::Revisions - Object capable of processing dump files with multiple revisions per article


This object is used to access the metadata associated with a MediaWiki instance and provide an iterative interface for extracting the indidivual article revisions out of the same. To gurantee that there is only a single revision per article use the Parse::MediaWikiDump::Revisions object.


  $pmwd = Parse::MediaWikiDump->new;
  $revisions = $pmwd->revisions('pages-articles.xml');
  $revisions = $pmwd->revisions(\*FILEHANDLE);
  #print the title and id of each article inside the dump file
  while(defined($page = $revisions->next)) {
    print "title '", $page->title, "' id ", $page->id, "\n";


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.



Open the specified MediaWiki dump file. If the single argument to this method is a string it will be used as the path to the file to open. If the argument is a reference to a filehandle the contents will be read from the filehandle as specified.


Returns an instance of the next available Parse::MediaWikiDump::page object or returns undef if there are no more articles left.


Returns a plain text string of the dump file format revision number


Returns a plain text string that is the name of the MediaWiki instance.


Returns the URL to the instances main article in the form of a string.


Returns a string containing 'MediaWiki' and a version number of the instance that dumped this file. Example: 'MediaWiki 1.14alpha'


Returns a string describing the case sensitivity configured in the instance.


Returns a reference to an array of references. Each reference is to another array with the first item being the unique identifier of the namespace and the second element containing a string that is the name of the namespace.


Returns an array reference the array contains strings of all the namespaces each as an element.


Returns the number of bytes that has been processed so far


Returns the total size of the dump file in bytes.
