Do keep in mind that wil's example will make foo equal to the characters between abc and xyz. i.e. $foo == "hello" if you are trying to extract to another variable you need to do something more like this. 
$foo = "abchelloxyz";
$foo =~ /abc([\w]+)xyz/;
$bar = $1;

the value of $foo is unchanged. ---Mogaka is good
