75978 Parsing Data

I am downloading html files with approximately 12 data fields per record. The file sizes are approximately 10K each. I want perl/cgi script that I can extract FName, LName, EmailAddress. I want the script written so that I can pass the file names as arguments to the script and the output file will have the same name with a .txt extension. I'm in a hurry to process these files. Thank You for looking at my project.
