Is this possible?

var allNodes = document.getElementsByTagName('*');
var node;
var nodeName;
for (var i = 0; i < allNodes.length; i++) {
    node = allNodes[i];
    nodeName = node.nodeName.toLowerCase();
    if (node.style) {
        for (var p in node.style) {
            node.style[p] = '';
        }
    }
    if ('style' == nodeName) {
        node.removeChild(node.firstChild);
    }
    if ('link' == nodeName) {
        node.href='';
    }
}
