This should have been post as a reply to parsing using metacharacters.

Can you post your code so we can see which part of it is giving you problems? Just reading the file and printing the data (just storing each chemical and not all) shouldnt use a lot of memory. Likewise if you save the data to the database as you read each one, that shouldnt be a problem.

What did you mean with 'using CGI'?, CGI isnt necessary to write data to a MySQL database.
