NAME

       HTTP::OAI::ListIdentifiers - Provide access to an OAI ListIdentifiers response

SYNOPSIS

               my $r = $h->ListIdentifiers;

               while(my $rec = $r->next) {
                       print "identifier => ", $rec->identifier, "\n",
                       print "datestamp => ", $rec->datestamp, "\n" if $rec->datestamp;
                       print "status => ", ($rec->status || 'undef'), "\n";
               }

               die $r->message if $r->is_error;

METHODS

       $li = new OAI::ListIdentifiers
           This constructor method returns a new OAI::ListIdentifiers object.

       $rec = $li->next
           Returns either an HTTP::OAI::Header object, or undef, if there are no more records.
           Use $rec->is_error to test whether there was an error getting the next record
           (otherwise things will break).

           If -resume was set to false in the Harvest Agent, next may return a string (the
           resumptionToken).

       @il = $li->identifier([$idobj])
           Returns the identifier list and optionally adds an identifier or resumptionToken,
           $idobj. Returns an array ref of HTTP::OAI::Headers.

       $dom = $li->toDOM
           Returns a XML::DOM object representing the ListIdentifiers response.

       $token = $li->resumptionToken([$token])
           Returns and optionally sets the HTTP::OAI::ResumptionToken.
