Python中使用SAX解析xml实例

import  sys, string from  xml.sax import  handler, make_parser
 
 class  TestHandler(handler.ContentHandler):                       
         def  __init__(self):                                                               
                 pass
                
         def  startDocument(self):           
                 print  "Document Start ..."
               
        def  endDocument(self):                
                print  "Document End ..."
               
        def  startElement(self, name, attrs):
                print  ‘start tag:‘, name
               
        def  endElement(self, name):
                print  ‘end tag:‘, name    
               
        def  characters(self, chrs):                                                    
                print  chrs
               
    
def  test():    
        handler = TestHandler()    
        parser = make_parser()    
        parser.setContentHandler(handler)
        f = open(sys.argv[1], ‘r‘)    
        parser.parse(f)    
        f.close()
    
if  __name__ == ‘__main__‘:
        test()
