hi there. You could just use the perl pattern matching to achieve this. it s very simple and easy. Just incorporate this below piece of code on your array.

@webserverlist = qw(server1:NY:3600 webserver1:NY:3600 server2:NY:3600
+ server3:NY:3600 webserver4:NY:3600 server4:Boston:3600);

foreach (@webserverlist)
{
if ( $_ =~ m/^web.*/ )
{
push (@list, $_."\n" );
}
}
print @list;

this will get all the WEB*servers into the array @list. enjoy scripting......
