Question

我想从XML响应中读取标记，该标记中包含很多命名空间。之前它可以正常工作，但是现在已经停止工作了：（

代码：

以下代码以前曾起作用，但现在不起作用

response = requests.post(url,data=body,headers=Headers)
tree = ET.fromstring(response.content)
lst = tree.find('.//Id').text
print('request submitted Request Id: '+str(lst))

Error:
Traceback (most recent call last):
  File "p3.py", line 179, in <module>
    lst = tree.find('.//Id').text
AttributeError: 'NoneType' object has no attribute 'text'

我尝试了“关注”，但大部分时间返回[] or None都不起作用。

st=(response.content)
st1=(st.decode('utf-8'))  
root=ET.fromstring(st1)

ID =root.findall("./findContractResponse/")
#root=tree.getroot()
#print(root.tag)
#print(root.attrib)

# xmlstr is your xml in a string
#root = lxml.etree.fromstring(st1)
#textelem = root.find('Body/findContractResponse/result/Value/Id')
#print (textelem.text)
namespaces = {'ns1': 'http://xmlns.oracle.com/apps/contracts/coreAuthoring/contractService/'}
ns1="http://xmlns.oracle.com/apps/contracts/coreAuthoring/contractService/"
#root = ET.fromstring(xml)
print(root.findall('ns1:Value', namespaces))
#str=root.findall('ns1:Value', namespaces)
#print(str)
print(root.find('{http://xmlns.oracle.com/apps/contracts/coreAuthoring/contractService/}Value'))

以下是我从SOAP请求获得的XML响应

伙计们，我被困在这里，我尝试使用elementree的所有选项，但注意会有所帮助。具有讽刺意味的是它以前曾经工作过，但我不知道为什么现在不工作
