简单一点的实现如下，如果要LIST哪几项，自己 切片取出来即可：

1. from xml.parsers.expat import ParserCreate
   
2. LIST = []
   
3. class DefaultSaxHandler(object):
   
4.     def start_element(self, name, attrs):
   
5.         #print('sax:start_element: %s, attrs: %s' % (name, str(attrs)))
   
6.         pass
   
7. 
   
8.     def end_element(self, name):
   
9.         #print('sax:end_element: %s' % name)
   
10.         pass
    
11. 
    
12.     def char_data(self, text):
    
13.          if  text == '    ' or text == '        ' or text == '\n':
    
14.              pass
    
15.          else:
    
16.              global LIST
    
17.              LIST == LIST.append(text)
    
18.              return LIST
    
19. 
    
20. xml = r'''<BCResponse>
    
21.     <processorHost>hhhhhdkksksks</processorHost>
    
22.     <responseCode>RJCT</responseCode>
    
23.     <pts_transaction_id>OY9Q6QMAXE6I</pts_transaction_id>
    
24.     <requestId>OY9Q6QMAXE6I</requestId>
    
25.     <responseCodeDescription>杀手</responseCodeDescription>
    
26.     <responseCodeDetail>NARR</responseCodeDetail>
    
27.     <responseStatus>REJECTED</responseStatus>
    
28.     <creditorName>电影</creditorName>
    
29.     <debtorName>Neil PAYMENTS-CN</debtorName>
    
30.     <remittanceType>CRDT</remittanceType>
    
31.     <requestedAmount xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="currencyPaymentAmount">
    
32.         <currencyValue>225.72 CNY (0.01)</currencyValue>
    
33.     </requestedAmount>
    
34. </BCResponse>
    
35. '''
    
36. 
    
37. handler = DefaultSaxHandler()
    
38. parser = ParserCreate()
    
39. parser.StartElementHandler = handler.start_element
    
40. parser.EndElementHandler = handler.end_element
    
41. parser.CharacterDataHandler = handler.char_data
    
42. parser.Parse(xml)
    
43. print(LIST)

复制代码

执行结果：
['hhhhhdkksksks', 'RJCT', 'OY9Q6QMAXE6I', 'OY9Q6QMAXE6I', '杀手', 'NARR', 'REJECTED', '电影', 'Neil PAYMENTS-CN', 'CRDT', '225.72 CNY (0.01)']
