NAME ^

Geo::Parse::OSM - OpenStreetMap XML file regexp parser

VERSION ^

version 0.42

SYNOPSIS ^

    use Geo::Parse::OSM;

    my $osm = Geo::Parse::OSM->new( 'planet.osm.gz' );
    $osm->seek_to_relations;
    $osm->parse( sub{ warn $_[0]->{id}  if  $_[0]->{user} eq 'Alice' } );

METHODS ^

new

Creates parser instance and opens file

    my $osm = Geo::Parse::OSM->new( 'planet.osm' );

Compressed files (.gz, .bz2) are also supported.

parse

Parses file and executes callback function for every object. Stops parsing if callback returns 'stop'

    $osm->parse( sub{ warn $_[0]->{id} and return 'stop' } );

It's possible to filter out unnecessary object types

    $osm->parse( sub{ ... }, only => 'way' );
    $osm->parse( sub{ ... }, only => [ 'way', 'relation' ] );

seek_to

Seeks to the file position or to the first object of selected type.

    $osm->seek_to( 0 );
    $osm->seek_to( 'way' );

Can be slow on compressed files!

seek_to_nodes

seek_to_ways

seek_to_relations

    $osm->seek_to_ways;     # same as seek_to('way');

parse_file

Class method - creates parser instance and does one parser() pass. Returns created parser object.

    use Data::Dumper;
    Geo::Parse::OSM->parse_file( 'planet.osm', sub{ print Dumper $_[0] } );

FUNCTIONS ^

object_to_xml

Returns xml representation of the callback object.

    sub callback {
        print Geo::Parse::OSM::object_to_xml( shift @_);
    }
    Geo::Parse::OSM->parse_file( 'planet.osm', \&callback );
