Få First Occurred-värdet från XML med hjälp av oracle parser

Jag antar att det här är vad du letar efter-

FOR r IN (  SELECT rownum rn, cells
           FROM xmltable('/SearchOutput/rowArray/Row' passing XMLTYPE(l_xmlclob)
                                     columns CELLS  XMLTYPE PATH './cellArray') f
        )
 LOOP
  DBMS_OUTPUT.PUT_LINE('Row: '||r.rn);      
  FOR c IN ( SELECT colid, 
                    colval
               FROM xmltable('for $i in /cellArray/Cell
                              return $i' 
                              passing r.cells
                              columns COLID NUMBER PATH 'columnId',
                                      COLVAL VARCHAR(20) PATH 'valueArray/Value[1]/value')                  
           )
  LOOP
     DBMS_OUTPUT.PUT_LINE('colid, col value: '||c.colid||', '||c.colval);
  END LOOP;
 END LOOP;
end;

ELLER

FOR r IN (  SELECT rownum rn, cells
           FROM xmltable('/SearchOutput/rowArray/Row' passing XMLTYPE(l_xmlclob)
                                     columns CELLS  XMLTYPE PATH './cellArray')
        )
 LOOP
  DBMS_OUTPUT.PUT_LINE('Row: '||r.rn);      

  FOR c IN ( SELECT colid, colval
               FROM xmltable('/cellArray/Cell' passing r.cells
                                               columns COLID NUMBER PATH './columnId',
                                                       COLVAL VARCHAR(20) PATH     './valueArray/Value[1]/value')
           )
  LOOP
     DBMS_OUTPUT.PUT_LINE('colid, col value: '||c.colid||', '||c.colval);
  END LOOP;
 END LOOP;

Utdata-

Row: 1
colid, col value: 1, Uganda
colid, col value: 5, AZ12604823-001
colid, col value: 2, IT06686
colid, col value: 9, Hu Mics Metab K
colid, col value: 8, 2006-06-21
colid, col value: 7, 2006-07-27

Value[1] ger dig det första av flerradselementet, dvs det första Value singel.
