You say in your email "All methods on the server require that you give
your user login and password (MD5 encoded) as strings in the first two
parameters."
You don't seem to be doing that. Your error message is generated
because you are giving the wrong number of parameters.
Replace: $f=new xmlrpcmsg('hpe.getSource', array('search term removed'));
With: $f=new xmlrpcmsg('hpe.getSource', new xmlrpcval($login), new
xmlrpcval($password), new xmlrpcval("18", 'int')));
The method 'getSource' can not search the newsisfree.com on a specific
string, you must specify the source ID you want. In this case, 18 is
used. If you want to grab news from more than one source, the third
parameter can be an array of source IDs. Ex.: array(new
xmlrpcval("18", 'int'),new xmlrpcval("19", 'int')).
See this: http://www.newsisfree.com/apixmlrpc.php?hpe=getSource#doc
