使用python解析xml成对应的html示例分享

1296次阅读  |  发布于5年以前

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

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

if callable(method): args = ()
else:
method = getattr(self, dname, None)

args = name

    #if prefix == 'start': args += attrs  
    if callable(method): method()
