Python 解析 HTTP SOAP 響應

我一直在關注HERE和HERE中的範例，嘗試解析 SOAP 響應，但無法獲得我想要的元素。

範例 SOAP 響應：

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
   xmlns="urn:partner.soap.sforce.com" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Body>
       <loginResponse>
           <result>
               <metadataServerUrl>meta</metadataServerUrl>
               <passwordExpired>false</passwordExpired>
               <sandbox>true</sandbox>
               <serverUrl>someUrl</serverUrl>
               <sessionId>sessionId###</sessionId>
               <userId>userId###</userId>
               <userInfo></userId>
           </result>
       </loginResponse>
   </soapenv:Body>
</soapenv:Envelope>

試圖取回sessionId但得到None或空的列表。

範常式式碼：

import xml.etree.ElementTree as ET

...


r = requests.post(url, headers=header, data=payload)

data = r.content

ns = {
   "soapenv": "http://schemas.xmlsoap.org/soap/envelope/"
}

root = ET.fromstring(data)

sid = root.findall(".//soapenv:sessionId", ns)

# Tried these and any combination of those
#sid = root.findall("./soapenv:Body/soapenv:loginResponse/soapenv:result/soapenv:sessionId", ns)
#sid = root.findall("./soapenv:Body/loginResponse/result/sessionId", ns)
#sid = root.findall("soapenv:sessionId", ns)

print(sid)

有人能幫忙嗎？

您一直在嘗試尋找錯誤的 ns.

這是工作範例：

import xml.etree.ElementTree as ET

data = """<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
   xmlns="urn:partner.soap.sforce.com" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Body>
       <loginResponse>
           <result>
               <metadataServerUrl>meta</metadataServerUrl>
               <passwordExpired>false</passwordExpired>
               <sandbox>true</sandbox>
               <serverUrl>someUrl</serverUrl>
               <sessionId>sessionId###</sessionId>
               <userId>userId###</userId>
               <userInfo></userInfo>
           </result>
       </loginResponse>
   </soapenv:Body>
</soapenv:Envelope>"""

root = ET.fromstring(data)

sid = root.findall(".//{urn:partner.soap.sforce.com}sessionId")
print(sid[0].text)
