NAME URI::NamespaceMap - Class holding a collection of namespaces VERSION Version 1.10 SYNOPSIS use URI::NamespaceMap; my $map = URI::NamespaceMap->new( { xsd => 'http://www.w3.org/2001/XMLSchema#' } ); $map->namespace_uri('xsd')->as_string; my $foaf = URI::Namespace->new( 'http://xmlns.com/foaf/0.1/' ); $map->add_mapping(foaf => $foaf); $map->add_mapping(rdf => 'http://www.w3.org/1999/02/22-rdf-syntax-ns#' ); $map->list_prefixes; # ( 'foaf', 'rdf', 'xsd' ) $map->foaf; # Returns URI::Namespace object while (my ($prefix, $nsURI) = $map->each_map) { $node->setNamespace($nsURI->as_string, $prefix); # For use with XML::LibXML } DESCRIPTION This module provides an object to manage multiple namespaces for creating URI::Namespace objects and for serializing. METHODS `new ( [ \%namespaces | @prefixes | @uris ] )` Returns a new namespace map object. You can pass a hash reference with mappings from local names to namespace URIs (given as string or RDF::Trine::Node::Resource) or namespaces_map with a hashref. You may also pass an arrayref containing just prefixes and/or namespace URIs, and the module will try to guess the missing part. To use this feature, you need RDF::NS::Curated, RDF::NS, XML::CommonNS or RDF::Prefixes, or preferably all of them. With that, you can do e.g. my $map = URI::NamespaceMap->new( 'rdf', 'xsd', 'foaf' ); and have the correct mappings added automatically. `add_mapping ( $name => $uri )` Adds a new namespace to the map. The namespace URI can be passed as string or a URI::Namespace object. `remove_mapping ( $name )` Removes a namespace from the map given a prefix. `namespace_uri ( $name )` Returns the URI::Namespace object (if any) associated with the given prefix. $name This module creates a method for all the prefixes, so you can say e.g. $map->foaf and get a URI::Namespace object for the FOAF namespace. Since URI::Namespace does the same for local names, you can then say e.g. $map->foaf->name to get a full URI. `list_namespaces` Returns an array of URI::Namespace objects with all the namespaces. `list_prefixes` Returns an array of prefixes. `each_map` Returns an 2-element list where the first element is a prefix and the second is the corresponding URI::Namespace object. `guess_and_add ( @string_or_uri )` Like in the constructor, an array of strings can be given, and the module will attempt to guess appropriate mappings, and add them to the map. `uri ( $prefixed_name )` Returns a URI for an abbreviated string such as 'foaf:Person'. prefix_for `uri ($uri)` Returns the associated prefix (or potentially multiple prefixes, when called in list context) for the given URI. abbreviate `uri ($uri)` Complement to "namespace_uri". Returns the given URI in `foo:bar` format or `undef` if it wasn't matched, therefore the idiom my $str = $nsmap->abbreviate($uri_node) || $uri->as_string; may be useful for certain serialization tasks. WARNING Avoid using the names 'can', 'isa', 'VERSION', and 'DOES' as namespace prefix, because these names are defined as method for every Perl object by default. The method names 'new' and 'uri' are also forbidden. Names of methods of Moose::Object must also be avoided. Using them will result in an error.
