Simple regex question

Hello,

Sorry to waste your time with this, but I'm new to regular expressions.
I, simply want to grab the text between two html tags:

various characters and whitespace <span id="title">Dog Eggs</title>
various characters and whitespace

I want a regex that notices the "title" id and grabs Dog Eggs for me.
I have one that works, but it's really kludgey.

Thanks,
Todd

DATA.read.scan( /id="title">(.*?)</m ) { |s|
  puts s
}

__END__

various characters and whitespace
<span id="title">Bird

irb(main):001:0> text = %(<span id="title">Dog Eggs</title>)
=> "<span id=\"title\">Dog Eggs</title>"
irb(main):002:0> text[%r(<span id="title">(.*?)</title>), 1]
=> "Dog Eggs"

I really like this interface.

regards,

Brian

Perfect, thanks! Didn't know about String.scan.
