# AnyEvent::XMPP::Namespaces(3pm)

XMPP namespace collection and aliasing class

## NAME

AnyEvent::XMPP::Namespaces - XMPP namespace collection and aliasing class

## SYNOPSIS

```
   use AnyEvent::XMPP::Namespaces qw/xmpp_ns set_xmpp_ns_alias/;
   set_xmpp_ns_alias (stanzas => 'urn:ietf:params:xml:ns:xmpp-stanzas');
```

## DESCRIPTION

This module represents a simple namespaces aliasing mechanism to ease handling of namespaces when traversing AnyEvent::XMPP::Node objects and writing XML with AnyEvent::XMPP::Writer.

## XMPP NAMESPACES

There are already some aliases defined for the XMPP XML namespaces which make handling of namepsaces a bit easier:

```
   stream  => http://etherx.jabber.org/streams
   xml     => http://www.w3.org/XML/1998/namespace
   streams => urn:ietf:params:xml:ns:xmpp-streams
   session => urn:ietf:params:xml:ns:xmpp-session
   stanzas => urn:ietf:params:xml:ns:xmpp-stanzas
   sasl    => urn:ietf:params:xml:ns:xmpp-sasl
   bind    => urn:ietf:params:xml:ns:xmpp-bind
   tls     => urn:ietf:params:xml:ns:xmpp-tls
   client  => jabber:client
   roster  => jabber:iq:roster
   version => jabber:iq:version
   auth    => jabber:iq:auth
   iq_oob  => jabber:iq:oob
   x_oob   => jabber:x:oob
   disco_info  => http://jabber.org/protocol/disco#info
   disco_items => http://jabber.org/protocol/disco#items
   register    => http://jabber.org/features/iq-register
   iqauth      => http://jabber.org/features/iq-auth
   data_form   => jabber:x:data
   ping        => urn:xmpp:ping
   vcard       => vcard-temp
   pubsub      => http://jabber.org/protocol/pubsub
   pubsub_own  => http://jabber.org/protocol/pubsub#owner
   pubsub_ev   => http://jabber.org/protocol/pubsub#event
```
