The basic algorithm is "sort and group":
  1. Read in your CVS file
  2. Sort the rows on id using sort - it is very flexible.
  3. Define a variable $currentId to store the current id. Initialize it as undef or a bogus value to insure that the first id read triggers the generation of XML for an order header.
  4. Loop through your records
    1. clean up bad data
    2. if id is the same as $currentId, generate the XML for an item
    3. if id is different, reset $currentId and print the XML for the order header.

Best, beth
