Python 解析XML文件

Python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()
