The first time through the outer foreach loop /filter_name =\s+(.*)/ matches so it goes through the inner loop where /REGEXP =\s+(.*)/ and then /OWNER =\s+(.*)/ and then /GROUP =\s+(.*)/ match in turn.

The second time through the outer foreach loop /vs_name =\s+(.*)/ matches.

The third time through the outer foreach loop /vs_owner =\s+(.*)/ matches.

Because of the way you capture the variable data, if the outer loop iterates again the regular expressions will not match and the variable $vsowner will cleared (set to undef).

Change each if/elsif expression from: 

if ( ( $variable ) = /pattern (.*)/ ) {

To: 

if ( /pattern (.*)/ ) {
    $variable = $1;
