引言

    为了学习xml-rpc，找到了一个xml-rpc的c语言的server/client实现，通过它的学习来掌握xml-rpc。

简述

     xmlrpc-epi是一个xml-rpc的c语言实现，但是它不包括传输层，像HTTP。现在最新版也支持SOAP1.1

使用范例

    可以使用这个库，实现服务器和客户端。

特征和体系结构

• 对值的操作有全面的API
• XML的分析（xml_element.c）是完全独立于XMLRPC接口库的。它能被当作一个独立的实现使用。
• Because of this, the same XMLRPC data can be serialized into multiple xml vocabularies. It is simply a matter of writing a transport. So far, two transports have been defined. The default xmlrpc vocab (xml_to_xmlrpc.c), and simple-rpc (xml_to_dandarpc.c) which is proprietary, but imho more readable, and nice for proprietary legacy reasons.
• Various output options, including: xml escaping via CDATA or entity, case folding, vocab version, and character encoding.
• support for converting UTF-8 (from xml parser) to local character encoding.
• One to One mapping between C structures and actual values, without developer having to know arcana of xmlrpc protocol.
• support for mixed indexed/keyed vector types, making it more compatible with languages such as PHP.
• quite speedy compared to implementations written in interpreted languages. Also, uses intelligent string handling, so not many strlen() calls, etc.

XMLRPC-EPI Architecture

解说

• Support Routines: 被系统使用的基本的实用程序
• XML Parser:  读入外部的XML数据，提供给xml_element来分析
• XML In Memory Tree: 这个程序负责读入和写出xml数据，它与xmlrpc无关，也能被用来做其他用途，如读取xml的配置文件。
• Vocabulary Serializers: 这个程序在xml和xmlrpc数据结构之间转换
• Application API: 这是应用程序使用的XMLRPC的API，它提供了容易的数据操作，方法注册和处理
