我正在尝试从 Python 中的字符串解析 XML，但没有成功。我试图解析的字符串是：

<?xml version="1.0" encoding="UTF-8"?>
<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:573a453c-72c0-4185-8c54-9010593dd102">
   <data>
      <config xmlns="http://www.calix.com/ns/exa/base">
         <profile>
            <policy-map>
               <name>ELINE_PM_1</name>
               <class-map-ethernet>
                  <name>Eth-match-any-1</name>
                  <ingress>
                     <meter-type>meter-mef</meter-type>
                     <eir>1000000</eir>
                  </ingress>
               </class-map-ethernet>
            </policy-map>
            <policy-map>
               <name>ELINE_PM_2</name>
               <class-map-ethernet>
                  <name>Eth-match-any-2</name>
                  <ingress>
                     <meter-type>meter-mef</meter-type>
                     <eir>10000000</eir>
                  </ingress>
               </class-map-ethernet>
            </policy-map>
         </profile>
      </config>
   </data>
</rpc-reply>

我正在尝试使用 xml.etree.ElementTree 库来解析 xml，并且我还尝试删除与 xml 版本和编码相关的第一行，但没有结果。重现我面临的问题的代码片段是：

import xml.etree.ElementTree as ET

reply_xml='''

   <config>
      <profile>
         <policy-map>
            <name>ELINE_PM_1</name>
            <class-map-ethernet>
               <name>Eth-match-any-1</name>
               <ingress>
                  <meter-type>meter-mef</meter-type>
                  <eir>1000000</eir>
               </ingress>
            </class-map-ethernet>
         </policy-map>

               <ingress>
                  <meter-type>meter-mef</meter-type>
                  <eir>10000000</eir>
               </ingress>
            </class-map-ethernet>

root = ET.fromstring(reply_xml) …
