What is XML-RPC?
It's a spec and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet.
他是一个规范和实现的集合，允许软件在异构系统中运行，运行在不同的环境中的程序通过Internet实现过程调用。
It's remote procedure calling using HTTP as the transport and XML as the encoding. XML-RPC is designed to be as simple as possible, while allowing complex data structures to be transmitted, processed and returned.
远程过程调用是采用HTTP传输Encoded XML.XML-RPC 设计得简单、可靠，允许复合的数据结构传输、处理和返回。
XML-RPC跨越所有的操作系统，编程语言，动态与静态环境，开源和商业化。主要语言有Perl、Python,Java,Frontier,C/C++,Lisp,PHP,Microsoft .NET,Rebol,Real Basic,Tcl,Delphi,WebObjects 和 Zope，还有更多将被加入进来。
