NAME
    XML::RPC -- Pure Perl implementation for an XML-RPC client and server.

SYNOPSIS
    make a call to an XML-RPC server:

        use XML::RPC;

        my $xmlrpc = XML::RPC->new('http://betty.userland.com/RPC2');
        my $result = $xmlrpc->call( 'examples.getStateStruct', { state1 => 12, state2 => 28 } );

    create an XML-RPC service:

        use XML::RPC;
        use CGI;

        my $q      = new CGI;
        my $xmlrpc = XML::RPC->new();
        my $xml    = $q->param('POSTDATA');

        print $q->header( -type => 'text/xml', -charset => 'UTF-8' );
        print $xmlrpc->receive( $xml, \&handler );

        sub handler {
            my ( $methodname, @params ) = @_;
            return { you_called => $methodname, with_params => \@params };
        }

DESCRIPTION
    XML::RPC module provides simple Pure Perl methods for XML-RPC communication. It's goals are
    simplicity and flexibility. XML::RPC uses XML::TreePP for parsing.

CONSTRUCTOR AND OPTIONS
  $xmlrpc = XML::RPC->new();
    This constructor method returns a new XML::RPC object. Usable for XML-RPC servers.

  $xmlrpc = XML::RPC->new( 'http://betty.userland.com/RPC2', %options );
    Its first argument is the full URL for your server. The second argument is for options passing
    to XML::TreePP, for example: output_encoding => 'ISO-8859-1' (default is UTF-8).

METHODS
  $xmlrpc->call( 'method_name', @arguments );
    This method calls the provides XML-RPC server's method_name with @arguments. It will return the
    server method's response.

  $xmlrpc->receive( $xml, \&handler );
    This parses an incoming XML-RPC methodCall and call the \&handler subref with parameters:
    $methodName and @parameters.

  $xmlrpc->xml_in();
    Returns the last XML that went in the client.

  $xmlrpc->xml_out();
    Returns the last XML that went out the client.

CUSTOM TYPES
  $xmlrpc->call( 'method_name', { data => sub { { 'base64' => encode_base64($data) } } } );
    When passing a CODEREF to a value XML::RPC will simply use the returned hashref as a type =>
    value pair.

ERROR HANDLING
    To provide an error response you can simply die() in the \&handler function. Also you can set
    the $XML::RPC::faultCode variable to a (int) value just before dieing.

PROXY SUPPORT
    Default XML::RPC will try to use LWP::Useragent for requests, you can set the environment
    variable: CGI_HTTP_PROXY to set a proxy.

LIMITATIONS
    XML::RPC will not create "bool", "dateTime.iso8601" or "base64" types automatically. They will
    be parsed as "int" or "string". You can use the CODE ref to create these types.
