I have a regular expression that looks like:

We're just looking for spaces with most of those .*?s, right? Why don't we say that. And between quotes we're looking for non-quote characters, right?
s/class\s*=\s*'[^']*'//sgi
greedy RegEx's are a good thing, except when they are TOO greedy!
Your RegEx is very Strong, but it is short by a leading \s*
my $foo = q{<table class='foo'><tr class='baz'><td class='bar'>};
print "First foo: $foo\n";
$foo =~ s/\s*class\s*=\s*'[^']*'//sgi;
print "Second foo: $foo\n";so that one does not wind up with
<table ><tr ><td >
with your CORRECT use of the "[^']*" - the "anything but '" match.
Folks need to remember to clear the 'white space' between the token and the attribute list! Which is an ugly we all do...
