Oddly i cannot find a simple answer to this rather important question anywhere on the web.

I am trying to extract ip address and port from multiple occurrences in a file. 

if ($_ =~ /[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}:[0-9]{1,5}:/
+) {print MYFILE2 "$_ \n";}

Will find it and print it if the line contains it.

BUT.. How do i match it and assign the IP address to a variable even if the string contains multiple addresses?

I had though i could split the file into words and then for each word compare but there has to be a better way.

Thanks in advance

Thank you for your quick reply MORITZ but what am i comparing and where do i assign the data? 

if ($_ =~ /[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}:[0-9]{1,5}:/
+) {print MYFILE2 "$_ \n";}

becomes 

while <$_> {
   while ([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}:[0-9]{1,5}/g)
+ {
   @iparray[$iparraycounter] = $1;
   $iparraycounter++;

}}

@iparray now contains just the ip addresses? $_= is the entire page with addresses
@iparray = list of addresses found

THANK YOU AnomalousMonk (P.s. I like the name :)

Your example is easy to follow and almost understood ... :)

I am abit confused as to where to insert the regex however.

p.s. Yup i am aware it will do 999. It will get kicked out later though. when i do a verify site is up.

I did try adding the following code but got an error: 

my $str = "br>94.198.240.132:60988 asdfasdf 174.142.24.201:3128 asdfas
+dfasdf";
 if (my @matches = $str =~ m{ ([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-
+9]{1,3}:[0-9]{1,5}) }xmsg) {
   print qq{matched @matches};
   }

I Tried removing the enclosing () 

$str =~ m{ [0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-
+9]{1,3}:[0-9]{1,5} }xmsg)

[download]
= same error

I Tried adding / / 

$str =~ m{ /[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-
+9]{1,3}:[0-9]{1,5}/ }xmsg)

= same error

Sorry will add a new message next time
