Oracle使用Sql把XML解析成表（Table）的方法

SELECT * FROM XMLTABLE('$B/DEAL_BASIC/USER_DEAL_INFO' PASSING
    XMLTYPE('<?xml version="1.0" encoding="gb2312" ?>
              <DEAL_BASIC>
                 <USER_DEAL_INFO>
                     <USER_DEAL_ID>1000100001</USER_DEAL_ID>
                     <DEAL_INURE_TIME>20081130</DEAL_INURE_TIME>
                     <DEAL_EXPIRE_TIME>30000101</DEAL_EXPIRE_TIME>
