*If* you're parsing HTML, it might be safer to use:
$newsFile =~ s/<B>//ig;
So that the entirely valid construction "<b>" will also be removed.
And, you might want the following instead:
$newsFile =~ s/<\/?B>//ig;
So that both open and close tags are removed.
This brings up another question for the gurus out there:
I tend to backslash just about all punctuation marks, especially those that
have special meaning(s) in perl. Thus I would have written:
$newsFile =~ s/\<\/?B\>//ig;
In general, is this a good habit on my part, or is it frowned upon because
it clutters the code? I've written perl in a vacuum for so long that I've
lost touch with the etiquette.
