How do I recursively search an object tree and return the matching object based on a key/value using JavaScript/Prototype 1.7

I've got some nested object data and I want to search it and return the matching object based on the id.

var data = [{id: 0, name: 'Template 0', subComponents:[
        {id: 1, name: 'Template 1', subItems:[
            {id: 2, name: 'Template 2', subComponents:[{id: 3, name: 'Template 3'}], subItems: [{id: 4, name: 'Template 4'}]}
        ]}
    ]}
];

So I want to do something like this

getObjectByKeyValue({id: 3}) 

and have it return

{id: 3, name: 'Template 3'}

It's sort of got to be done generically because I have subItems, AND subComponents which could each have children.

I tried this using Prototype 1.7 and no luck - I think this just searches an array, and not a tree with it's sub nodes:

data.find(function(s){return s.id == 4;})

Thanks in advance!!!!!!
