ruby gives more (objects), see http://ruby-doc.org/core/classes/MatchData.html

some simple examples

t="Title123asdf"
#=> "Title123asdf"
/^Title([a-zA-Z0-9])/.match(t)
#=> #<MatchData:0x28b7b60>
/^Title([a-zA-Z0-9])/.match(t)[0]
#=> "Title1"
/^Title([a-zA-Z0-9])/.match(t)[1]
#=> "1"
$~
#=> #<MatchData:0x28afc94>
$~[0]
#=> "Title1"
$~[1]
#=> "1"
x=/^Title([a-zA-Z0-9])/.match(t)
#=> #<MatchData:0x28a8598>
x[0]
#=> "Title1"
x[1]
