Some old (2001) instructions for accessing XML-RPC using Perl. Also take a look at the XML-RPC Perl tutorial on xml-rpc.com !

Update 2003-01-29

According to a customer the information below is indeed outdated ;-) Apparently the Frontier module is not available anymore, instead you can use the SOAP::Lite module which not only provides SOAP, but also XML-RPC client functionality.
A small code snippet to access OpenGroupware.org:

use XMLRPC::Lite;
use Data::Dumper; $Data::Dumper::Terse = 1; $Data::Dumper::Indent = 1;
> 
my $fkt  = "person.getById";
my $para = "10000";
> 
my $result = XMLRPC::Lite
        -> proxy('http://root:rootpwd@165.0.0.10:20000')
        -> $fkt($para);

print Dumper($result->paramsall), '';

XMLRPC support for Perl - README

Installation

To use XMLRPC with Perl, you first need these Perl modules installed on your machine (SuSE 7.2 tested) :

• perl-libwww-perl
• perl-XML-Parser

If you untar'ed and ungzip'ed the package, you just need to issue the following commands to install the client on your system :

• perl Makefile.PL
• make
• make test (check if everything is OK here)
• make install (you should be 'root')

How to use it

To show you how to use Perl and XMLRPC to access a OGo server, here's a little code example that shows the essential steps.

#!/usr/bin/perl

# 'include' the XMLRPC client
use Frontier::Client;

# init the client with the target url, login & password
$client = Frontier::Client->new( url => 
                  "http://login:password@your.server.com:10000");

# send a message to fetch persons with a name like 'zaphod',
# store the result in @result
@result = $client->call('person.fetch',"name like \'*zaphod*\'");

# check how many records we received
$count = @{$result[0]}; 

# iterate over the results
for $i (0 .. $count-1)
{
  # get the current element
  $element = $result[0]->[$i];

  # get the name of the current element
  $name = $element->{"name"};
}
