Re: Re: How do I use regex to strip out specific characters in a string?

RE notes: A few things to take note of since it seems that you may include those qualifiers on all matches which are not always needed or wanted.

The o says to only compile the RE once which is the case anyway since the pattern is a literal.
the s folds lines in the match to one big line making . match \n which in this match a noop.
the i makes the match case insensitive which slows down the match. Additionally, the : is not affected by case.
the x allows comments to be included in the match none of which have been included.
as noted before tr/://d ( or y/://d ) is much more efficient to eliminate or change single characters.
