标题: [zz]python expat 解析xml

来源：

主题：解析xml文本
      环境： winxp pro + sp2 + python2.5
      备注：请注意，凡是在源代码文件中使用了中文字符，请最好保存为utf-8格式
                  测试用例sample.xml也请用utf-8格式保存
      代码：

python 代码

# 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()
测试用例：
xml 代码：sample.xml

xml version="1.0"?>

contacts id="bluecrystal">
item name="keen" fff="ddd">

telephone type="phone">222222222telephone>
telephone type="mobile">134567890telephone>

item>
item name="bcm">

telephone type="phone">11111111telephone>
telephone type="mobile">15909878909telephone>

item>
contacts>
      测试结果：
Start element: contacts {'id': 'bluecrystal'}

Start element: item {'fff': 'ddd', 'name': 'keen'}
Start element: telephone {'type': 'phone'}

Character data: 222222222
End element: telephone

Start element: telephone {'type': 'mobile'}
Character data: 134567890

End element: telephone
End element: item

Start element: item {'name': 'bcm'}
Start element: telephone {'type': 'phone'}

Character data: 11111111
End element: telephone

Start element: telephone {'type': 'mobile'}
Character data: 15909878909

End element: telephone
End element: item

End element: contacts
