例如用戶達蓋特這樣做：

select * 
FROM XMLTABLE('/person/row' 
     PASSING 
      xmltype(' 
       <person> 
        <row> 
         <name>Tom</name> 
         <Address> 
          <State>California</State> 
          <City>Los angeles</City> 
         </Address> 
        </row> 
        <row> 
         <name>Jim</name> 
         <Address> 
          <State>California</State> 
          <City>Los angeles</City> 
         </Address> 
        </row> 
       </person> 
      ') 
     COLUMNS 
      --describe columns and path to them: 
      name varchar2(20) PATH './name', 
      state varchar2(20) PATH './Address/State', 
      city varchar2(20) PATH './Address/City' 
    ) xmlt 
;

with data as 
(select '<a><c>1</c><c>2</c></a>' xmlval 
from dual) 
(select c 
    from data d, 
     xmltable('/a/*' passing xmltype(d.xmlval) 
     columns 
    c varchar2(254) path '/c'
