John Coggeshall has a new posting over on his blog today about his latest XML-RPC release - the improved XML-RPC extension (XMLRPCi) 1.0-beta.

Today I released the first public beta of XML-RPCi -- an improved XML-RPC extension for PHP 5+. Built upon the libxml2 library it supports object overloading and automatic fault handling as interfaces for XML-RPC requests.

It makes using namespaces in XML-RPC communications a bit easier, as well as integrating error checking (such as with try/catch). Since it is in beta, head on over, download it, and test it out. I'm sure John would live to get a few bug reports...
