With Perl you can surround the data you want with ()'s and pull it out later, perhaps other languages have a similar feature.

if ($s_output =~ /(data data data data START(data data data)END (data data)/) 
{
    $dataAllOfIt = $1;      # 1 full string
    $dataInMiddle = $2;     # 2 Middle Data
    $dataAtEnd = $3;        # 3 End Data
}
