[转]Python解析xml文本
Python:1. # parsexml.py
2. # 本例子参考自python联机文档，做了适当改动和添加
3.
4. import xml.parsers.expat
5.
6. # 控制打印缩进
7. level = 0
8.
9. # 获取某节点名称及属性值集合
10. def start_element(name, attrs):
11. global level
12. print ' '*level, 'Start element:', name, attrs
13. level = level + 1
14.
15. # 获取某节点结束名称
16. def end_element(name):
17. global level
18. level = level - 1
19. print ' '*level, 'End element:', name
20.
21. # 获取某节点中间的值
22. def char_data(data):
23. if(data == '\n'):
24. return
25. if(data.isspace()):
26. return
27. global level
28. print ' '*level, 'Character data:', data
29.
30. p = xml.parsers.expat.ParserCreate()
31.
32. p.StartElementHandler = start_element
33. p.EndElementHandler = end_element
34. p.CharacterDataHandler = char_data
35. p.returns_unicode = False
36.
37. f = file('sample.xml')
38. p.ParseFile(f)
39. f.close()
Sample.xml
1. <xml version="1.0"?>
2. <contacts id="bluecrystal">
3. <item name="keen" fff="ddd">
4. <telephone type="phone">222222222telephone>
5. <telephone type="mobile">134567890telephone>
6. </item>
7. <item name="bcm">
8. <telephone type="phone">11111111telephone>
9. <telephone type="mobile">15909878909telephone>
10. </item>
11. </contacts>
Output:
1. Start element: contacts {'id': 'bluecrystal'}
2. Start element: item {'fff': 'ddd', 'name': 'keen'}
3. Start element: telephone {'type': 'phone'}
4. Character data: 222222222
5. End element: telephone
6. Start element: telephone {'type': 'mobile'}
7. Character data: 134567890
8. End element: telephone
9. End element: item
10. Start element: item {'name': 'bcm'}
11. Start element: telephone {'type': 'phone'}
12. Character data: 11111111
13. End element: telephone
14. Start element: telephone {'type': 'mobile'}
15. Character data: 15909878909
16. End element: telephone
17. End element: item
18. End element: contacts
