Oracle SQL - Convert given list (CSV) into Rows

Just a quick note as to something that worked for me. Taken from the Oracle forums @ https://forums.oracle.com/forums/thread.jspa?messageID=6861756

Situation
I have one column of values that I've suffixed a comma to but I want to display this as a rows in a table. This is for Oracle PL/SQL.

My List:
copyraw
1,
2,
3,
4,
5,
6
  1.  1, 
  2.  2, 
  3.  3, 
  4.  4, 
  5.  5, 
  6.  6 
Yields:
copyraw
1,2,3,4,5,6
  1.  1,2,3,4,5,6 

Using this snippet
copyraw
SELECT EXTRACT (VALUE (d), '//row/text()').getstringval () AS AppNo
  FROM (SELECT XMLTYPE (   ''
                        || REPLACE (
'1,
2,
3,
4,
5,
6'                    
                        , ',', '')
                        || ''
                       ) AS xmlval
          FROM DUAL) x,
       TABLE (XMLSEQUENCE (EXTRACT (x.xmlval, '/rows/row'))) d
  1.  SELECT EXTRACT (VALUE (d), '//row/text()').getstringval () AS AppNo 
  2.    FROM (SELECT XMLTYPE (   '' 
  3.                          || REPLACE ( 
  4.  '1, 
  5.  2, 
  6.  3, 
  7.  4, 
  8.  5, 
  9.  6' 
  10.                          , ',', '') 
  11.                          || '' 
  12.                         ) AS xmlval 
  13.            FROM DUAL) x, 
  14.         TABLE (XMLSEQUENCE (EXTRACT (x.xmlval, '/rows/row'))) d 
Yields:
copyraw
1
2
3
4
5
6
  1.  1 
  2.  2 
  3.  3 
  4.  4 
  5.  5 
  6.  6 

Note that I actually used text in the example above and this worked. Obviously don't get the commas mixed up.
