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。

复制代码 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:
    def dispatch(self, prefix, name, attrs=None):
        mname = prefix + name.capitalize()
        dname = 'default' + prefix.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()

    def startElement(self, name, attrs):
