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
