Question

我收到此xml响应，有人可以帮助我从xml标签获取令牌吗？

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><LoginResponse xmlns="http://videoos.net/2/XProtectCSServerCommand"><LoginResult xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><RegistrationTime>2018-09-06T07:30:38.4571763Z</RegistrationTime><TimeToLive><MicroSeconds>3600000000</MicroSeconds></TimeToLive><TimeToLiveLimited>false</TimeToLiveLimited><Token>TOKEN#xxxxx#</Token></LoginResult></LoginResponse></s:Body></s:Envelope>

我将其作为字符串

也尝试使用lxml和其他类似ET的库，但无法提取令牌字段。 HELPPP

使用xml格式更新，以方便阅读，仅供参考。

<?xml version="1.0" encoding="utf-8"?>

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body>
    <LoginResponse xmlns="http://videoos.net/2/XProtectCSServerCommand">
      <LoginResult xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <RegistrationTime>2018-09-06T07:30:38.4571763Z</RegistrationTime>
        <TimeToLive>
          <MicroSeconds>3600000000</MicroSeconds>
        </TimeToLive>
        <TimeToLiveLimited>false</TimeToLiveLimited>
        <Token>TOKEN#xxxxx#</Token>
      </LoginResult>
    </LoginResponse>
  </s:Body>
</s:Envelope>

Answer 1

使用lxml

演示：

x = '''<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body>
    <LoginResponse xmlns="http://videoos.net/2/XProtectCSServerCommand">
      <LoginResult xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <RegistrationTime>2018-09-06T07:30:38.4571763Z</RegistrationTime>
        <TimeToLive>
          <MicroSeconds>3600000000</MicroSeconds>
        </TimeToLive>
        <TimeToLiveLimited>false</TimeToLiveLimited>
        <Token>TOKEN#xxxxx#</Token>
      </LoginResult>
    </LoginResponse>
  </s:Body>
</s:Envelope>'''

from lxml import etree
xmltree = etree.fromstring(x)
namespaces = {'content': "http://videoos.net/2/XProtectCSServerCommand"}
items = xmltree.xpath('//content:Token/text()', namespaces=namespaces)
print(items)

输出：

['TOKEN#xxxxx#']
