Hi,
Need to delete a node from xml data having many nodes with same name. I have tried by using DELETEXML in the following way.

My test xml is...

with data as (
      select XMLTYPE('<ROWSET>
  <ROW>
    <TABLE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>1 </VERS_MINOR>
    </TABLE_T>
   </ROW>
   <ROW>
    <POST_TABLE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>1 </VERS_MINOR>
    </POST_TABLE_T>
   </ROW>
  </ROWSET>') val 
     from dual
     )
   select DELETEXML(val,'ROWSET/ROW/POST_TABLE_T') val
   from data



The output is...

<ROWSET>
  <ROW>
    <TABLE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>1 </VERS_MINOR>
    </TABLE_T>
  </ROW>
  [color=red][b]<ROW />[/b][/color]
</ROWSET>


I got an extra '<ROW />' node in the output. Shall i need to delete the extra part? If yes...how?
Or any alternative to delete a node from xml.

Regards,
Madhavi.

Only you know if you have to do it. It is your data and only you know what you want to do with them.

Finally i'm expecting the output as below.

<ROWSET>
  <ROW>
    <TABLE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>1 </VERS_MINOR>
    </TABLE_T>
  </ROW>
  </ROWSET>



How can i get that.
Regards,
Madhavi.

You can use:
with data as (
      select XMLTYPE('<ROWSET>
  <ROW>
    <TABLE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>1 </VERS_MINOR>
    </TABLE_T>
   </ROW>
   <ROW>
    <POST_TABLE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>1 </VERS_MINOR>
    </POST_TABLE_T>
   </ROW>
  </ROWSET>') val 
     from dual
     )
   select  DELETEXML(val,'ROWSET/ROW[POST_TABLE_T]')
   from data
