如何用python解析xml响应？

我从API调用中获得XML响应（使用python）。如何解析xml响应

xml响应：

200 OK
<?xml version='1.0' encoding='UTF-8' ?>
<mail>
 <delivery id='123'>
  <deliver_id>xxx</deliver_id>
  <request_id>xxx</request_id>
  <exec_cnt>1</exec_cnt>
  <result code='0'>success</result>
 </delivery>
</mail>

def sendMail():
    context = ssl._create_unverified_context()
    header = {"Content-Type": "text/xml"}
    url = "xxx"
    body = "xxx"
    try:
            conn = http.client.HTTPSConnection("54.199.162.74", context=context)
            conn.request(method="POST", url=url, body=body.encode("UTF-8"), headers=header, encode_chunked=True)
            response = conn.getresponse()
            mail_response = response.read()
            print(response.status, response.reason)
            print(mail_response.decode('utf-8'))
    except Exception as e:
            print(e)
    return response

sendMail()

我试图用这段代码解析xml响应，但总是返回错误

import xml.etree.ElementTree as ET
response_xml_as_string = mail_response.decode('utf-8')

>>> tree = ET.fromstring(response_xml_as_string)
>>> root = tree.getroot()
>>> root.tag
'mail'
>>> root.attrib
{}
>>> for child in root:
...     print(child.tag, child.attrib)

我得到的错误是：

'xml.etree.ElementTree.Element'对象没有属性'getroot'

---

ElementTree

实例没有

getroot

属性。您将从树的根开始，然后可以使用

iter（tree）

迭代子元素：

将xml.ElementTree作为ET导入
resp=”“”
xxx
xxx
1.
成功
"""
tree=ET.fromstring（resp）
目录（树）
# “UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU"初始","初始","子类","减小","减小","减小","减小",titem_uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
#这里没有getroot方法
#只需迭代每个元素
对于树中的元素：
打印（elem.text，elem.attrib）
如果elem.getchildren（）：
#也要重复它们

您还可以使用BeatuifulSoup解析和提取内容

from bs4 import BeautifulSoup as Soup
resp = """<?xml version='1.0' encoding='UTF-8' ?>
<mail>
 <delivery id='123'>
  <deliver_id>xxx</deliver_id>
  <request_id>yyy</request_id>
  <exec_cnt>1</exec_cnt>
  <result code='0'>success</result>
 </delivery>
</mail>"""

soup = Soup(resp,'xml')
#extracting data between request_id Tag
print(soup.request_id.get_text())

#extracting data between deliver ID Tag
print(soup.deliver_id.get_text())

#extracting the  result code and the data between the tag
print(soup.result['code'])
print(soup.result.get_text())

从bs4导入BeautifulSoup作为汤
resp=”“”
xxx
yyy
1.
成功
"""
汤=汤（分别为'xml'）
#提取请求与id标记之间的数据
打印（soup.request\u id.get\u text（））
#在deliver-ID标签之间提取数据
打印（soup.deliver\u id.get\u text（））
#提取结果代码和标记之间的数据
打印（soup.result['code']）
打印（soup.result.get_text（））

通过您的代码，我可以获得交付id、请求id、执行id、结果消息（成功）的值。但我仍然不知道如何获得结果代码（0）。您知道如何获得它吗？
