I'm creating a CSS editor and am trying to create a regular expression that can get data from a CSS document. This regex works if I have one property but I can't get it to work for all properties. I'm using preg/perl syntax in PHP.

Regex

(?<selector>[A-Za-z]+[\s]*)[\s]*{[\s]*((?<properties>[A-Za-z0-9-_]+)[\s]*:[\s]*(?<values>[A-Za-z0-9#, ]+);[\s]*)*[\s]*}

Test case

body { background: #f00; font: 12px Arial; }

Expected Outcome

Array(
    [0] => Array(
            [0] => body { background: #f00; font: 12px Arial; }
            [selector] => Array(
                [0] => body
            )
            [1] => Array(
                [0] => body
            )
            [2] => font: 12px Arial; 
            [properties] => Array(
                [0] => font
            )
            [3] => Array(
                [0] => font
            )
            [values] => Array(
                [0] => 12px Arial
                [1] => background: #f00
            )
            [4] => Array(
                [0] => 12px Arial
                [1] => background: #f00
            )
        )
)

Real Outcome

Array(
    [0] => Array
        (
            [0] => body { background: #f00; font: 12px Arial; }
            [selector] => body 
            [1] => body 
            [2] => font: 12px Arial; 
            [properties] => font
            [3] => font
            [values] => 12px Arial
            [4] => 12px Arial
        )
    )

Thanks in advance for any help - this has been confusing me all afternoon!
