Python - 如何解析 xml 响应并将元素值存储在变量中？

Question

我从 API 调用获取 XML 响应。

我需要此响应中的“testId”属性值。请帮我解决这个问题。

r = requests.get( myconfig.URL_webpagetest + "?url=" + testurl + "&f=xml&k=" + myconfig.apikey_webpagetest )
xmltxt = r.content
print(xmltxt)
testId = XML(xmltxt).find("testId").text
r = requests.get("http://www.webpagetest.org/testStatus.php?f=xml&test=" + testId )

xml响应：

<?xml version="1.0" encoding="UTF-8"?>
<response>
    <statusCode>200</statusCode>
    <statusText>Ok</statusText>
    <data>
        <testId>180523_YM_054fd7d84fd4ea7aed237f87289e0c7c</testId>
        <ownerKey>dfc65d98de13c4770e528ef5b65e9629a52595e9</ownerKey>
        <jsonUrl>http://www.webpagetest.org/jsonResult.php?test=180523_YM_054fd7d84fd4ea7aed237f87289e0c7c</jsonUrl>
    </data>
</response>

产生以下错误：

Traceback (most recent call last):
  File "/pagePerformance.py", line 52, in <module>
    testId = XML (xmltxt).find("testId").text
AttributeError: 'NoneType' object has no attribute 'text'

使用以下命令从响应中收集 testId：-

import xml.etree.ElementTree as ET

response_xml_as_string = "xml response string from API"
responseXml = ET.fromstring(response_xml_as_string)
testId = responseXml.find('data').find('testId')
print testId.text
