Regular Expressions

Case-insensitive pattern matching

To achieve a case-insensitive pattern matching, add the i modifier after the closing slash of the regular expression.

Example:

When searching for HTML tags, we preferably do a case-insensitive search. e.g.:
if ($doc =~ /<TABLE.*>/i) {
   ___;
   ___;
   ___;
}

# This would match <TABLE...>, <table>, <TAblE>, etc.
