This is a real newbie question. I've got Perl on my Mac OS X box. I want to search through a text file for ID numbers and then look in a database of replacements for the text. The database can be a text file with any delimiters for records. At the end, I just want the text file with ID numbers replaced by the corresponding text. I don't want to have to keep the database around to read the resulting file.

(The application is to take a web page with IDs for pictures of 400 kids (randomly sorted) in a science fair and replace the IDs with their name and city they come from. Then, I'll serve the new web page.)

Any help would be appreciated. Particularly if there is an existing tool or some keywords I can use to find such a tool.
