Scala multiline string extraction using regular expression

Question

Given a collection of strings which start all with prefix _abc_ABC( and end with suffix ), for instance,

val a = """_abc_ABC(
{
  x = 1
  y = 2
})"""

how to define a regular expression that strips out the prefix and suffix above ?

Must it be a regex? Simple String manipulation might be easier. — semptic, Aug 26 '14 at 09:18
@semptic true, `stripPrefix` and `stripSuffix` would make it, yet would like to know with regex... — elm, Aug 26 '14 at 09:19

This would work:

val a = """_abc_ABC(
{
  x = 1
  y = 2
})"""

val Re = """(?s)_abc_ABC\((.*)\)""".r
a match { case Re(content) => println(content) }

The (?s) makes it match over multiple lines.
