Maybe Stupid RegEx Question

[Bastian Angerstein]

Hi

I have two strings 0x1479ee und 0x1479fe.

The strings a in $var1 and $var2.

if I do:
if ( $var2 =~ /\Q$var1\E/)

It matches.

how can I match an the string and not on each sign?

You sure about that?

#!/usr/bin/perl

my($var1, $var2) = ("0x1479ee", "0x1479fe");

if ($var2 =~ /\Q$var1\E/) { print "They matched.\n"; }
else { print "They didn't match.\n"; }

__END__

The above gives me "They didn't match." as expected.

The obvious answer is that they can't. Because of that, those
variables probably don't contain what you think they contain.

Hope that helps.

As someone else pointed out, I am surprised that you got a match...
Just out of curiosity though, why not do this:

if ( $var2 eq $var1 )

Wouldn't that achieve what you want?
