Python 解析XML文件

#parsexml.py

#本例子参考自python联机文档，做了适当改动和添加

import xml.parsers.expat

#控制打印缩进

level = 0

#获取某节点名称及属性值集合

def start_element(name, attrs):

global level

print ' '*level, 'Start element:', name, attrs

level = level + 1

#获取某节点结束名称

def end_element(name):

global level

level = level - 1

print ' '*level, 'End element:', name

#获取某节点中间的值

def char_data(data):

if(data == '\n'):

return

if(data.isspace()):

return

global level

print ' '*level, 'Character data:', data

p = xml.parsers.expat.ParserCreate()

p.StartElementHandler = start_element

p.EndElementHandler = end_element

p.CharacterDataHandler = char_data

p.returns_unicode = False

f = file('sample.xml')

p.ParseFile(f)

f.close()
