Remove All id Attributes from nodes in a Range of Fragment

Question

Is there a way to remove the id attribute of every node in a range or fragment?

Update: I finally found out that the bug I'm struggling with is based on a <[script]> being included in a range, and therefore unexpectedly cloned, when a chrome user does a ctrl+a. My goal would be to remove any instance of <[script]> from the range (or doc fragment), such that it is not replicated when cloned.

You may be able to use a TreeWalker, which works in pretty much all the browers that Range works in.

function actOnElementsInRange(range, func) {
    function isContainedInRange(el, range) {
        var elRange = range.cloneRange();
        elRange.selectNode(el);
        return range.compareBoundaryPoints(Range.START_TO_START, elRange) <= 0
                && range.compareBoundaryPoints(Range.END_TO_END, elRange) >= 0;
    }

    var rangeStartElement = range.startContainer;
    if (rangeStartElement.nodeType == 3) {
        rangeStartElement = rangeStartElement.parentNode;
    }

    var rangeEndElement = range.endContainer;
    if (rangeEndElement.nodeType == 3) {
        rangeEndElement = rangeEndElement.parentNode;
    }

    var isInRange = function(el) {
        return (el === rangeStartElement || el === rangeEndElement ||
                    isContainedInRange(el, range))
            ? NodeFilter.FILTER_ACCEPT : NodeFilter.FILTER_SKIP;
    };

    var container = range.commonAncestorContainer;
    if (container.nodeType != 1) {
        container = container.parentNode;
    }

    var walker = document.createTreeWalker(document,
        NodeFilter.SHOW_ELEMENT, isInRange, false);

    while (walker.nextNode()) {
        func(walker.currentNode);
    }
}

actOnElementsInRange(range, function(el) {
    el.removeAttribute("id");
});
