regex - Parse SVG transform attribute with javascript

Question

Supposing we have an SVG transform string:

transform = "translate(6,5),scale(3,3)";

Is there a slick regex function we could use to parse that into something usable?

Answer 1

Here's a nifty little snippet of code that might get you what you need, it should cover most scenario in case the string you intend to parse has different number of arguments:

function parse (a)
{
    var b={};
    for (var i in a = a.match(/(w+((-?d+.?d*e?-?d*,?)+))+/g))
    {
        var c = a[i].match(/[w.-]+/g);
        b[c.shift()] = c;
    }
    return b;
}

Running this

parse('translate(6,5),scale(3,3.5),a(1,1),b(2,23,-34),c(300)');

Will result in this:

{
    translate: [ '6', '5' ],
    scale: [ '3', '3.5' ],
    a: [ '1', '1' ],
    b: [ '2', '23', '-34' ],
    c: [ '300' ]
}
