For more information about XMPP visit: http://www.xmpp.org =head1 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. =head1 EXAMPLES use Net::XMPP; my $client = Net::XMPP::Client->new(); =head1 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 equivilant 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: =head2 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. =head2 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. InsertRawXML(string) - puts the specified string raw into the XML packet that you call this on. $message->InsertRawXML("") ... $x = $message->NewChild(..); $x->InsertRawXML("test"); $query = $iq->GetChild(..); $query->InsertRawXML("test"); ClearRawXML() - removes the raw XML from the packet. =head2 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. =head2 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"); =head1 PACKAGES For more information on each of these packages, please see the man page for each one. =head2 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. =head2 Net::XMPP::Protocol A collection of high-level functions that Client uses to make their lives easier. These methods are inherited by the Client. =head2 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. =head2 Net::XMPP::Message Everything needed to create and read a received from the server. =head2 Net::XMPP::Presence Everything needed to create and read a received from the server. =head2 Net::XMPP::IQ IQ is a wrapper around a number of modules that provide support for the various Info/Query namespaces that XMPP recognizes. =head2 Net::XMPP::Stanza This module represents a namespaced stanza that is used to extend a , , and . 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. =head2 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. =head1 AUTHOR Ryan Eatmon =head1 COPYRIGHT This module is free software, you can redistribute it and/or modify it under the same terms as Perl itself. =cut require 5.005; use strict; use XML::Stream 1.22 qw( Node ); use Time::Local; use Carp; use Digest::SHA1; use Authen::SASL; use MIME::Base64; use POSIX; use vars qw( $AUTOLOAD $VERSION $PARSING ); $VERSION = "1.0"; use Net::XMPP::Debug; use Net::XMPP::JID; use Net::XMPP::Namespaces; use Net::XMPP::Stanza; use Net::XMPP::Message; use Net::XMPP::IQ; use Net::XMPP::Presence; use Net::XMPP::Protocol; use Net::XMPP::Client; ############################################################################## # # printData - debugging function to print out any data structure in an # organized manner.
