If there is nothing else in your regular expression, then you can use the simple solution others have suggested 

    /<%.*?%>/

but if you have other bits in the regex, then you may need to "unroll the loop" like we did in the bad old regex days before we had non-greedy qualifiers: 
    m[
      <%        # Opening delimiter.
      (?:       # Match stuff that isn't a closing delim:
        [^%]+     # Things that can't start one.
      | %+[^%>]   # Might start one but isn't one.
      )*        # As many non-closing-delims as you like.
      %>        # Closing delimiter.
    ]x

but it doesn't look like you need to. I just thought you might find the more general case interesting. (:
