Python 解析 HTTP SOAP 响应

我一直在关注这里和这里尝试解析 SOAP 响应，但无法获取我想要的元素。

SOAP 响应示例：

<?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>

尝试获取sessionId但None返回的是空列表。

示例代码：

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)

有人能帮忙吗？

您尝试搜索错误的 ns。

以下是工作示例：

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)
