Loop through user text fields on a page

Question

I am new to APEX and I have searched for an answer to this problem, but was not able to find one.
I have a page which has about 40 text boxes for user input. I would like to find a way to loop through all of the text boxes on the page when the user submits the form. I want to check the contents of each text box and filter out any characters that are not alpha or numeric. I would like to do this in one process. Is this possible? If so, how would I access the text boxes and remove the unwanted input? Could you please show me an example?
Thanks for any guidance on this.

Hi,
I did not test this, but could something like after submit process work
DECLARE
l_temp VARCHAR2(32000);
BEGIN
  FOR C IN
  (SELECT item_name
  FROM apex_application_page_items
  WHERE display_as   = 'Text Field'
  AND application_id = :APP_ID
  AND page_id        = :APP_PAGE_ID
  LOOP
    -- Do stuff e.g. remove character  Ö
    l_temp := REPLACE(v(c.item_name),'Ö');
    APEX_UTIL.SET_SESSION_STATE (
      p_name  => c.item_name,
      p_value => l_temp
  END LOOP;
END;Br,Jari
