【Java】将xml解析成对应的html
作者:宝仔love / 发布于2014/4/3/ 623
用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

试试其它关键字
　将xml解析　
同语言下
可能有用的
