# Text between

Uses /^/ and /$/ as start and end delimiters. Additionally, the start and end delimiters can be regular expressions.

```ruby
func text_between (text, beg, end) {

    beg.escape! if beg.kind_of(String)
    end.escape! if end.kind_of(String)

    Regex("#{beg}(.*?)(?:#{end}|\\z)", 's').match(text)[0] \\ ""
}

var tests = [
    Hash(
        text  => "Hello Rosetta Code world",
        start => "Hello ",
        end   => " world",
        out   => "Rosetta Code",
    ),
    Hash(
        text  => "Hello Rosetta Code world",
        start => /^/,
        end   => " world",
        out   => "Hello Rosetta Code",
    ),
    Hash(
        text  => "Hello Rosetta Code world",
        start => "Hello ",
        end   => /$/,
        out   => "Rosetta Code world",
    ),
    Hash(
        text  => "</div><div style=\"chinese\">你好嗎</div>",
        start => "<div style=\"chinese\">",

    assert_eq(t{:out}, r)
    say "text_between(#{t{:text}.dump}, #{t{:start}.dump}, #{t{:end}.dump}) = #{r.dump}"
