=head1 NAME

XML::LibXML::Namespace - XML::LibXML Namespace Implementation

=head1 SYNOPSIS

  use XML::LibXML;
  # Only methods specific to Namespace nodes listed here,
  # see XML::LibXML::Node manpage for other methods

  my $ns = XML::LibXML::Namespace->new($nsURI);
  print $ns->nodeName();
  print $ns->name();
  $localname = $ns->getLocalName();
  print $ns->getData();
  print $ns->getValue();
  print $ns->value();
  $known_uri = $ns->getNamespaceURI();
  $known_prefix = $ns->getPrefix();


=head1 DESCRIPTION

Namespace nodes are returned by both $element->findnodes('namespace::foo') or
by $node->getNamespaces().

The namespace node API is not part of any current DOM API, and so it is quite
minimal. It should be noted that namespace nodes are not a sub class of
XML::LibXML::Node, however Namespace nodes act a lot like attribute nodes, and
similarly named methods will return what you would expect if you treated the
namespace node as an attribute. Note that in order to fix several
inconsistencies between the API and the documentation, the behavior of some
functions have been changed in 1.64.

=item B<new>

  my $ns = XML::LibXML::Namespace->new($nsURI);

Creates a new Namespace node. Note that this is not a 'node' as an attribute or
an element node. Therefore you can't do call all XML::LibXML::Node Functions.
All functions available for this node are listed below.

Optionally you can pass the prefix to the namespace constructor. If this second
parameter is omitted you will create a so called default namespace. Note, the
newly created namespace is not bound to any document or node, therefore you
should not expect it to be available in an existing document.


=item B<declaredURI>

Returns the URI for this namespace.


=item B<declaredPrefix>

Returns the prefix for this namespace.


=item B<nodeName>

  print $ns->nodeName();

Returns "xmlns:prefix", where prefix is the prefix for this namespace.


=item B<name>

  print $ns->name();

Alias for nodeName()


=item B<getLocalName>

  $localname = $ns->getLocalName();

Returns the local name of this node as if it were an attribute, that is, the
prefix associated with the namespace.


=item B<getData>

  print $ns->getData();

Returns the URI of the namespace, i.e. the value of this node as if it were an
attribute.


=item B<getValue>

  print $ns->getValue();

Alias for getData()


=item B<value>

  print $ns->value();

Alias for getData()


=item B<getNamespaceURI>

  $known_uri = $ns->getNamespaceURI();

Returns the string "http://www.w3.org/2000/xmlns/"


=item B<getPrefix>

  $known_prefix = $ns->getPrefix();

Returns the string "xmlns"
