Hi all

I have a few regexp that checks input from the user to rule out any mailicious code.

here's an example 
$adress1 =~ /^([A-Za-z0-9öäåÖÄÅ][A-Za-zöäåÖÄÅ0-9\s\-\.\,]*)$/;
$adress1 = $1;
$adress2 =~ /^([A-Za-z0-9öäåÖÄÅ][A-Za-zöäåÖÄÅ0-9\s\-\.\,]*)$/;
$adress2 = $1;

[download]
But if $adress2 doesn't contain anything OR containing anyhing that will make the regexp fail, $adress2 eq $adress1 after these rows.
Why doesn't $1 reset when the regexp doesn't match anything?
Any ideas?

Best regards
/Jocke

In reply to $1 don't reset (non loop) by jockel
