NAME

       Net::XMPP - XMPP Perl Library

SYNOPSIS

         Net::XMPP provides a Perl user with access to the Extensible
         Messaging and Presence Protocol (XMPP).

         For more information about XMPP visit:

           http://www.xmpp.org

DESCRIPTION

         Net::XMPP is a convenient tool to use for any perl script that would
         like to utilize the XMPP Instant Messaging protocol.  While not a
         client in and of itself, it provides all of the necessary back-end
         functions to make a CGI client or command-line perl client feasible
         and easy to use.  Net::XMPP is a wrapper around the rest of the
         official Net::XMPP::xxxxxx packages.

         There is are example scripts in the example directory that provide you
         with examples of very simple XMPP programs.

         NOTE: The parser that XML::Stream::Parser provides, as are most Perl
         parsers, is synchronous.  If you are in the middle of parsing a packet
         and call a user defined callback, the Parser is blocked until your
         callback finishes.  This means you cannot be operating on a packet,
         send out another packet and wait for a response to that packet.  It
         will never get to you.  Threading might solve this, but as of this
         writing threading in Perl is not quite up to par yet.  This issue will
         be revisted in the future.

EXAMPLES

             use Net::XMPP;
             my $client = new Net::XMPP::Client();

METHODS

         The Net::XMPP module does not define any methods that you will call
         directly in your code.  Instead you will instantiate objects that call
         functions from this module to do work.  The three main objects that
         you will work with are the Message, Presence, and IQ modules. Each one
         corresponds to the Jabber equivalent and allows you get and set all
         parts of those packets.

         There are a few functions that are the same across all of the objects:

   Retrieval functions
         GetXML() - returns the XML string that represents the data contained
                    in the object.

                    $xml  = $obj->GetXML();

         GetChild()          - returns an array of Net::XMPP::Stanza objects
         GetChild(namespace)   that represent all of the stanzas in the object
                               that are namespaced.  If you specify a namespace
                               then only stanza objects with that XMLNS are
                               returned.

                               @xObj = $obj->GetChild();
                               @xObj = $obj->GetChild("my:namespace");

         GetTag() - return the root tag name of the packet.

         GetTree() - return the XML::Stream::Node object that contains the data.
                     See XML::Stream::Node for methods you can call on this
                     object.

   Creation functions
         NewChild(namespace)     - creates a new Net::XMPP::Stanza object with
         NewChild(namespace,tag)   the specified namespace and root tag of
                                   whatever the namespace says its root tag
                                   should be.  Optionally you may specify
                                   another root tag if the default is not
                                   desired, or the namespace requres you to set
                                   one.

                                   $xObj = $obj->NewChild("my:namespace");
                                   $xObj = $obj->NewChild("my:namespace","foo");
                                     ie. <foo xmlns='my:namespace'...></foo>

         InsertRawXML(string) - puts the specified string raw into the XML
                                packet that you call this on.

                                $message->InsertRawXML("<foo></foo>")
                                  <message...>...<foo></foo></message>

                                $x = $message->NewChild(..);
                                $x->InsertRawXML("test");

                                $query = $iq->GetChild(..);
                                $query->InsertRawXML("test");

         ClearRawXML() - removes the raw XML from the packet.

   Removal functions
         RemoveChild()          - removes all of the namespaces child elements
         RemoveChild(namespace)   from the object.  If a namespace is provided,
                                  then only the children with that namespace are
                                  removed.

   Test functions
         DefinedChild()          - returns 1 if there are any known namespaced
         DefinedChild(namespace)   stanzas in the packet, 0 otherwise.
                                   Optionally you can specify a namespace and
                                   determine if there are any stanzas with that
                                   namespace.

                                   $test = $obj->DefinedChild();
                                   $test = $obj->DefinedChild("my:namespace");

PACKAGES

         For more information on each of these packages, please see the man page
         for each one.

   Net::XMPP::Client
         This package contains the code needed to communicate with an XMPP
         server: login, wait for messages, send messages, and logout.  It uses
         XML::Stream to read the stream from the server and based on what kind
         of tag it encounters it calls a function to handle the tag.

   Net::XMPP::Protocol
         A collection of high-level functions that Client uses to make their
         lives easier.  These methods are inherited by the Client.

   Net::XMPP::JID
         The XMPP IDs consist of three parts: user id, server, and resource.
         This module gives you access to those components without having to
         parse the string yourself.

   Net::XMPP::Message
         Everything needed to create and read a <message/> received from the
         server.

   Net::XMPP::Presence
         Everything needed to create and read a <presence/> received from the
         server.

   Net::XMPP::IQ
         IQ is a wrapper around a number of modules that provide support for
         the various Info/Query namespaces that XMPP recognizes.

   Net::XMPP::Stanza
         This module represents a namespaced stanza that is used to extend a
         <message/>, <presence/>, and <iq/>.

         The man page for Net::XMPP::Stanza contains a listing of all supported
         namespaces, and the methods that are supported by the objects that
         represent those namespaces.

   Net::XMPP::Namespaces
         XMPP allows for any stanza to be extended by any bit of XML.  This
         module contains all of the internals for defining the XMPP based
         extensions defined by the IETF.  The documentation for this module
         explains more about how to add your own custom namespace and have it
         be supported.

BUGS

       Probably. There is at least one issue with XLM::Stream providing different node structures
       depending on how the node is created. Net::XMPP should now be able to handle this, but who
       knows what else lurks.
