示例二、
1、需要解析的文件app.xml

 
 
  
  
   com.mysql.jdbc.Driver
  
  
  
   
       jdbc:mysql://localhost:3306/tie?useUnicode=true&characterEncoding=utf-8
   
  
  
  
   root
  
  
  
   123
  
 
 
   class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  
   
  
  
  
   
    com/alonely/vo/User.hbm.xml
   
  
 
 
 
   class="org.springframework.orm.hibernate3.HibernateTemplate">
  
   
  
 
 
 
  
   
  
 
 
 
  
   
  
 
 
 
  
   
  
 

2、解析的代码etXml.py

# -*- coding:UTF-8 -*-

import xml.etree.ElementTree as ET

#获取所有节点
def getAllBean():
    root = ET.parse('app.xml').getroot()
    beans = root.findall('bean')

    #显示所有bean
    for bean in beans:
#        print ET.tostring(bean, 'UTF-8')
#        print '==========================================='
        pass

    return beans;

#获取所有property节点，以字典的的形式返回，属性名/property节点
def getAllProperty():
    beans = getAllBean()
    propList = {}
    for bean in beans:
        propertysE = bean.findall('property')
        for prop in propertysE:
            proname = prop.get('name')
            propList[proname] = prop
#            print ET.tostring(prop, 'UTF-8')
#            print '==========================================='
    return propList


#根据bean的属性id获取bean的class属性值
def getBeanClassAttr(beanid):
    bean = getBeanById(beanid)
    return bean.get('class')#获取节点属性为class的值

#根据id获取bean节点
def getBeanById(beanid):
    beans = getAllBean()
    for bean in beans:
        id = bean.get('id')#获取属性名为id的值
        if beanid == id:
            return bean

#根据bean的属性id获取其所有property节点
def getPropertysByBeanid(beanid):
    bean = getBeanById(beanid)
    props = bean.findall('property')
    return props;

#根据bean的属性id和property的名称获取实际值
def getPropertyValue(beanid,proname):
    props = getPropertysByBeanid(beanid)
    for prop in props:
        name = prop.get('name')
        if proname == name:
            valueE = prop.find('value')
            if valueE != None:
                return valueE.text


if __name__ == '__main__':

    print getPropertyValue('userService','userDAO')
