Python-如何解析xml响应并将元素值存储在变量中? [英] Python - How to parse xml response and store a elements value in a variable?

问题描述

enter code here我正在从API调用中获取XML响应.

enter code hereI am getting the XML response from the API call.

我需要此响应中的"testId"属性值，请对此提供帮助.

I need the "testId" attribute value from this response, Please help me on this.

   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>

以下错误正在响应-

回溯(最近通话最近): 文件"/pagePerformance.py"，第52行，在 testId = XML(xmltxt).find("testId").text AttributeError:'NoneType'对象没有属性'text'

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

推荐答案

使用以下命令从响应中收集testId:-

Use the following to collect testId from response:-

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
