删除<TRANSPORT>当中的除了指定的某些节点的其它的节点，比如指定OMCH，<TRANSPORT>当中只保留OMCH这个节点，<TRANSPORT>当中的其它节点删除。指定的节点可以是用户自己给出，可以是多个，请问如何实现呢，谢谢xml删除节点

           <IPRT>
              <attributes>
                <CN>0</CN>
                <DESCRI>default</DESCRI>
                <DSTIP>0.0.0.0</DSTIP>
                <DSTMASK>0.0.0.0</DSTMASK>
                <NEXTHOP>10.77.185.254</NEXTHOP>
                <PREF>60</PREF>
                <RTTYPE>0</RTTYPE>
                <SBT>0</SBT>
                <SN>7</SN>
                <SRN>0</SRN>
                <IFT>-1</IFT>
                <IFNO>-1</IFNO>
              </attributes>
            <CERTCHKTSK>
这个少了一个</IPRT>,应该为：
           <IPRT>
              <attributes>
                <CN>0</CN>
                <DESCRI>default</DESCRI>
                <DSTIP>0.0.0.0</DSTIP>
                <DSTMASK>0.0.0.0</DSTMASK>
                <NEXTHOP>10.77.185.254</NEXTHOP>
                <PREF>60</PREF>
                <RTTYPE>0</RTTYPE>
                <SBT>0</SBT>
                <SN>7</SN>
                <SRN>0</SRN>
                <IFT>-1</IFT>
                <IFNO>-1</IFNO>
              </attributes>
            </IPRT>
          <CERTCHKTSK>
