Question

我有一个SOAP服务器设置，它接收来自外部服务器的SOAP消息。我希望能够处理这些消息。感谢我服务器中的这两行代码，我能够在控制台中看到这些消息：

logging.basicConfig(level=logging.INFO)
logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)

无论如何我可以将此消息转换为字符串然后转换为对象实例吗？我知道这不是pythonic，最好的方法是设置一个与服务器WSDL匹配的WSDL，但这超出了我的编程能力，目前还没有WSDL解析器库，我可以使用无论是。

这是我想从控制台中显示的外部服务器处理的示例消息。

<Item xsi:type="Dp_Data">
    <UCPTname>Net/MB485/MAIN POWER/Fb/PowerSum</UCPTname>
    <UCPTlastUpdate>2014-04-04T13:34:17.441-04:00</UCPTlastUpdate>
    <UCPTformatDescription>#0000000000000000[0].SNVT_power_f#SI</UCPTformatDescription>
    <UCPTvalue LonFormat="#0000000000000000[0].SNVT_power_f#SI">9330.949</UCPTvalue>
    <UCPTpointStatus>AL_OFFLINE</UCPTpointStatus>
    <UCPTpriority>255</UCPTpriority>
    <UCPTpropagate>0</UCPTpropagate>
</Item>

我想将此消息转换为字符串，然后可能是一个对象实例，其中item将具有属性UCPTname，UCPTlastUpdate，UCPTvalue等。

请回复。

这是完整的信息：

您应该安装SoapPy（不要Soapy，请注意）并查看SOAP定义的可能类型（here）。

然后你可以像这样解析你的消息：

import SOAPpy
import logging
logging.getLogger().setLevel(logging.DEBUG)

item_str='<?xml version="1.0" encoding="utf-8"?>\
         <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" \

            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">\

                <Item xsi:type="Dp_Data">\

                    <UCPTvalue LonFormat="#0000000000000000[0].SNVT_power_f#SI">9330.949</UCPTvalue>\

                    <UCPTpropagate>0</UCPTpropagate>\
                </Item>\
            </soap:Body>\
        </soap:Envelope>'
expected = { 'Item': {

logging.debug("Last update: %s" % (item['UCPTlastUpdate'],))

logging.debug("Should this be propagated? %s" % ('Yeep' if item['UCPTpropagate'] else 'Nopes'))
