Yes, use non-greedy matching: .*?

>> a = <<EOS
   <my_tag>
        aaa
    </my_tag>
    <my_tag>
        text bla bla
    </my_tag>
EOS
=> "   <my_tag>\n        aaa\n    </my_tag>\n    <my_tag>\n        text 
bla bla\n    </my_tag>\n"
>> a.scan(%r{<my_tag>(.*?)</my_tag>}m)
=> [["\n        aaa\n    "], ["\n        text bla bla\n    "]]
