Please help getting invalid number error.

Question

Hi Experts,
My requirement is
If DT_ID value of xmlmsg existed in the DT_ID of PART_ID_COLLES table then that record should be processd else should be skipped.
And xmlmsg of PART_ID should start with "A" and followed only by the number then that record should be processed else should be skipped.
And xmlmsg of DD_DAYS should contain only  the number and grater than or equal to 0 ,then that record should be processed else should be skipped.
For that I have written this code.
But if I pass dt_id as string value in xmlmsg I am getting invalid number error.
DT_ID of PART_ID_COLLES table is number data type.
SELECT xmlmsg.part_id part_id,xmlmsg.dd_days dd_days,xmlmsg.dt_id dt_id
                  FROM XMLTABLE(
                        XMLNAMESPACES(
                            'urn:schemas-microsoft-com:rowset' as "rs"
                          , '#RowsetSchema' as "z"
                        '/z:row[not(@dt_id=following-sibling::z:row/@dt_id and @part_id=following-sibling::z:row/@part_id)]'
                        PASSING p_dd_days_vals
                        COLUMNS
                            ITEM_NO             for ordinality
                          , dt_id    VARCHAR2 (20) path '@dt_id'
                          , part_id  VARCHAR2 (25) path '@part_id'
                          , dd_days  VARCHAR2 (20) path '@dd_days'
                       ) xmlmsg,
                       part_id_colles pic
                       WHERE REGEXP_REPLACE(TRIM(xmlmsg.dt_id),'^([0-9]+)$|.','\1') = pic.dt_id
                             AND REGEXP_LIKE (UPPER(TRIM(xmlmsg.part_id)),'^[A][0-9]+$')
                             AND (TO_NUMBER(REGEXP_REPLACE(TRIM(xmlmsg.dd_days),'^([0-9]+)$|.','\1')) >=0
                             AND REGEXP_LIKE(TRIM(xmlmsg.dd_days), '^-?[[:digit:],.]*$') ;
Sample message is

Your code has ton of errors. Anyway:
with part_id_colles as (
                        select 430 dt_id,xmltype('<MESSAGES>
