Hi,
How to append root node (as ROWSET) to a variable in pl/sql.
I have the below xml data in a variable. I want to append a root node to the xml data exists in the variable.
I have the below data in a variable.
<ROW>
  <TABLESPACE_T>
    <VERS_MAJOR>1</VERS_MAJOR>
    <VERS_MINOR>0 </VERS_MINOR>
  </TABLESPACE_T>
</ROW>


finally i'm expecting the below xml data.

<ROWSET>
 <ROW>
  <TABLESPACE_T>
    <VERS_MAJOR>1</VERS_MAJOR>
    <VERS_MINOR>0 </VERS_MINOR>
  </TABLESPACE_T>
 </ROW>
</ROWSET>


Which function is useful?

Regards,
Madhavi.

OK, my fault I should post a complete valid syntax, I thought you will be able to understand.
It is:
'<ROWSET>'||your_variable||'</ROWSET>'

i have tried like that also but another error.

V_XML1 := '<ROWSET>'||V_XML||'</ROWSET>' ;
PLS-00306: wrong number or types of arguments in call to '||'


i used two single quotes also like below.
V_XML1 := ''<ROWSET>''||V_XML||''</ROWSET>'' ;

error is..

ERROR line 15, col 35, ending_line 15, ending_col 35, Found '>', Expecting: ;   -or-   OR   -or-   AND   -or-   ||   -or-   /   -or-   **   -or-   (+)   -or-   %  .

Use conversion: declare v_xml as varchar2(something) and use xmltype() function to convert the result of the concatenation.

Or:
SELECT XMLELEMENT
("ROWSET",
  XMLType('
  <ROW>
    <TABLESPACE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>0 </VERS_MINOR>
    </TABLESPACE_T>
  </ROW>')
 )xmlstr FROM dual;

XMLSTR
----------------------
<ROWSET>
  <ROW>
    <TABLESPACE_T>
      <VERS_MAJOR>1</VERS_MAJOR>
      <VERS_MINOR>0 </VERS_MINOR>
    </TABLESPACE_T>
  </ROW>
</ROWSET>
