Regular expressions are a big subject and we introduce them early to give trainees plenty of opportunity to try them out during our Perl courses ... we follow up later in the course with a second (and more advanced) module that shows you how to extract the text that matched, do substitutions, and more. We also cover regular expressions on our Tcl, PHP and Python courses ... and regular expressions are even relevant to MySQL and Apache httpd.
