Instead of messing with html you should submit the tree data in a more programmer-friendly format.

$('#saveButton').click(function() {
    var treeData = $.tree.reference($('#sortableTree')).get(undefined, 'json');
    var tmp = serializeTree(treeData, 0);
    // now json-encode tmp and submit it
});

function serializeTree(nodes, parent)
{
    var parents = {};
    var childOrder = []
    var childOrders = {};
    for(var i = 0; i < nodes.length; i++)
    {
        var node = nodes[i];
        var id = node.attributes.id.substr(5); // assuming the id looks like 'abcd-ID'
        parents[id] = parent;
        childOrder.push(id);
        if(node.children)
        {
            var tmp = serializeTree(node.children, id);
            for(var id in tmp[0])
                parents[id] = tmp[0][id];
            for(var id in tmp[1])
                childOrders[id] = tmp[1][id]
        }
    }

    childOrders[parent] = childOrder;

    return [parents, childOrders];
}
