def extract_goal_type(data): 
    #print(data) 
    if data : 
     root = ET.fromstring(data) 
     tree = ET.ElementTree(root) 
     root = tree.getroot() 
     for c in root.getchildren(): 
      return c.findtext('subtype') 

的問題是，該功能僅返回第一個子集和L似乎無法得到其他... ...你還擁有面向了XML文件到6個孩子。請l可如何解析這個得到的一切是在XML幫助....謝謝

您從for循環重新調諧，你必須遍歷所有元素然後返回數據。

def extract_goal_type(data): 
    #print(data) 
    ret_data = [] 
    if data : 
     root = ET.fromstring(data) 
     tree = ET.ElementTree(root) 
     root = tree.getroot() 
     for c in root.getchildren(): 
      ret_data.append(c.findtext('subtype')) 
    return ret_data 

注：如果您有有效的XML
