Multiple cursors and xmlforest

Question

This is my first time working with XML in PLSQL. I'm trying to parse values from a plsql procedure into a Word document using XML.
My procedure looks something like:
CREATE OR REPLACE PROCEDURE GET_XML_FA
(PP_ID IN VARCHAR2,
PP_PERIOD IN VARCHAR2
IS
result CLOB;
result1 clob;
CURSOR my_cur_1 IS
   SELECT XMLForest(to_char(sysdate,'fmMonth DD, YYYY') "sysdate",
                    INITCAP(TRIM(p.p_name))||' ('||p.p_id||')' "person",
                    p_period "period",
                    (SELECT DISTINCT INITCAP(TO_CHAR(det.detail_date,'fmMonth DD,YYYY'))
                     FROM details_table det, abc_table abc, people p
                     WHERE det.fa_seq_num = abc.fa_seq_num
                     AND p.p_seq_num = abc.p_seq_num
                     AND p.p_id LIKE pp_id
                     AND REPLACE((TO_CHAR(abc.from_period,'fmMonth YYYY'))||'-'||INITCAP(TO_CHAR(abc.thru_period,'fmMonth YYYY')),' ','') LIKE pp_period
                     AND det.dtl_code = 'bill'
                     ) "bill_date"            
                    ) xrow
FROM PEOPLE p
WHERE p.p_id = PP_ID;
CURSOR my_cur_2 IS 
                    select XMLForest
                    (Initcap(to_char(det.detail_date,'fmMonth DD,YYYY')) "payment_date",
                     det.detail_amt "payment_amt") xrow
                    from details_table det, abc_table abc, people p
                    where det.fa_seq_num = abc.fa_seq_num
                    and p.p_seq_num = abc.p_seq_num
                    and p.p_id = pp_id
                    AND replace((TO_CHAR(abc.from_period,'fmMonth YYYY'))||'-'||INITCAP(TO_CHAR(abc.thru_period,'fmMonth YYYY')),' ','') like pp_period
                    and det.dtl_code = 'payment';
BEGIN
htp.print('<?xml version="1.0" ?>');
htp.print('<DOCUMENT DOCNAME="My_Letter'||pp_id||'_'||pp_period||'.doc" DESTINATION="'||get_const_value('FA_TRACK_DIR')||'" SOURCE="'||get_const_value('DOCBUILDER_DIR')||'" LOGFILE="'||get_const_value('FA_TRACK_DIR')||'">');
htp.print('<NOTE FNAME="My_Letter.doc">');
  for my_rec_1 in my_cur_1 loop
  result := my_rec_1.xrow.getClobVal();
   htp.print(result);
  end loop;
  for my_rec_2 in my_cur_2 loop
  result1 := my_rec_2.xrow.getClobVal();
  htp.print(result1);
  end loop;
  htp.print('</NOTE>');
  htp.print('</DOCUMENT>');
END;my_cur_1 returns a single row of data whereas my_cur_2 returns multiple rows. However, while parsing values into my word document, my_cur_2 passes only the first row and doesn't pass the remaining rows.
I'm not able to understand what I am doing wrong. Can anyone help?
Note: get_const_value is our custom function that determines directory path based on server.
Let me know if more details are required.

Hi Scorpio,
my point was very simple. XMLAgg function pre-aggregates the result elements in one row. See example below with simulated dual data.
select XMLForest
(rownum "payment_date", 'a' "payment_amt" ) xrow
from dual connect by level <= 2
XROW
<payment_date>1</payment_date><payment_amt>a</payment_amt>
<payment_date>2</payment_date><payment_amt>a</payment_amt>
2 rows selected
select XMLAgg(XMLForest
(rownum "payment_date", 'a' "payment_amt" )) xrow
from dual connect by level <= 2
XROW
<payment_date>1</payment_date><payment_amt>a</payment_amt><payment_date>2</payment_date><payment_amt>a</payment_amt>
1 rows selected
If this doesn't help I'd suggest - simplify the example (consider only the cursor causing problem, use the dual table etc) and post the Oracle version.
