NAME
XML::Stream::Namespace - Object to make defining Namespaces easier in XML::Stream. SYNOPSIS
XML::Stream::Namespace is a helper package to XML::Stream. It provides a clean way of defining Namespaces for XML::Stream to use when connecting. DESCRIPTION
This module allows you to set and read elements from an XML::Stream Namespace. METHODS
SetNamespace("mynamespace"); SetXMLNS("http://www.mynamespace.com/xmlns"); SetAttributes(attrib1=>"value1", attrib2=>"value2"); GetNamespace() returns "mynamespace" GetXMLNS() returns "http://www.mynamespace.com/xmlns" GetAttributes() returns a hash ( attrib1=>"value1",attrib2=>"value2") GetStream() returns the following string: "xmlns:mynamespace='http://www.nynamespace.com/xmlns' mynamespace:attrib1='value1' mynamespace:attrib2='value2'" EXAMPLES
$myNamespace = new XML::Stream::Namespace("mynamspace"); $myNamespace->SetXMLNS("http://www.mynamespace.org/xmlns"); $myNamespace->SetAttributes(foo=>"bar", bob=>"vila"); $stream = new XML::Stream; $stream->Connect(name=>"foo.bar.org", port=>1234, namespace=>"foo:bar", namespaces=>[ $myNamespace ]); # # The above Connect will send the following as the opening string # of the stream to foo.bar.org:1234... # # <stream:stream # xmlns:stream="http://etherx.jabber.org/streams" # to="foo.bar.org" # xmlns="foo:bar" # xmlns:mynamespace="http://www.mynamespace.org/xmlns" # mynamespace:foo="bar" # mynamespace:bob="vila"> # AUTHOR
