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。

代码如下:

#!/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
#---------------------------------------
from xml.sax.handler import ContentHandler
from xml.sax import parse

class Dispatcher:

mname = prefix + name.capitalize()

method = getattr(self, mname, None)
if callable(method): args = ()
else:
method = getattr(self, dname, None)
#args = name
#if prefix == 'start': args += attrs
if callable(method): method()

self.dispatch('start', name, attrs)
