使用python解析xml成对应的html示例分享

SAX将dd.xml解析成html。当然啦，如果得到了xml对应的xsl文件可以直接用libxml2将其转换成html。

#!/usr/bin/env python 
# -*- coding: utf-8 -*-
#---------------------------------------
#   程序：XML解析器
#   版本：01.0
#   作者：mupeng
#   日期：2013-12-18
#   语言：Python 2.7
#   功能：将xml解析成对应的html
#   注解：该程序用xml.sax模块的parse函数解析XML，并生成事件
#   继承ContentHandler并重写其事件处理函数
#   Dispatcher主要用于相应标签的起始、结束事件的派发
