Answer 1

well, let's start from the inside and work our way out, shall we?
the "WITH" clause is just to alias a subquery that he used as an example. I'll assume you know that, and just put it inside the main query (and I'll use all the columns)
select rpad(t.column_value.getrootelement(),20) || ': ' || t.column_value.extract('//text()') out
from table(xmlsequence(xmltype(cursor(select * from emp where rownum<4)).extract('ROWSET/ROW/*'))) t
SQL> select cursor(select * from emp where rownum<4) from dual;
CURSOR(SELECT*FROMEM
CURSOR STATEMENT : 1
CURSOR STATEMENT : 1

1 row selected.
now that we know what that looks like, we can put it in the TABLE() and make it the FROM clause
SQL> select * from table(xmlsequence(xmltype(cursor(select * from emp where rownum<4)).extract('ROWSET/ROW/*')));

23 rows selected.I'm getting bored. I'm sure you can break down the remaining parts of the statement to see what they return, and how it all comes together.
