Python使用minidom读写xml的方法

<?xml version="1.0" encoding="UTF-8" ?> 
<employees>  
 <employee>  
  <name>l inux </name> 
  <age> 30 </age> 
 </employee> 
 <employee>  
  <name>windows </name> 
  <age> 20 </age> 
 </employee> 
</employees>

def TestMiniDom(): 
  from xml.dom import minidom 
  doc = minidom.parse( "employees.xml" ) 
  # get root element: <employees/> 
  root = doc.documentElement 
  # get all children elements: <employee/> <employee/> 
  employees = root.getElementsByTagName( "employee" ) 
  for employee in employees: 
    print ( " ------------------------------------------- " ) 
    # element name : employee 
    print (employee.nodeName) 
    # element xml content : <employee><name>windows</name><age>20</age></employee> 
    # basically equal to toprettyxml function 
    print (employee.toxml()) 
    nameNode = employee.getElementsByTagName( "name" )[0] 
    print (nameNode.childNodes) 
    print (nameNode.nodeName +  ":"  + nameNode.childNodes[0].nodeValue) 
    ageNode = employee.getElementsByTagName( "age" )[0] 
    print (ageNode.childNodes) 
    print (ageNode.nodeName +  ":"  + ageNode.childNodes[0].nodeValue) 
    print ( " ------------------------------------------- " ) 
    for n in employee.childNodes: 
      print (n)
