My goal is to remove all <[script]> nodes from a document fragment (leaving the rest of the fragment intact) before inserting the fragment into the dom.

My fragment is created by and looks something like this:

    range = document.createRange();
    range.selectNode(document.getElementsByTagName("body").item(0));
    documentFragment = range.cloneContents();
    sasDom.insertBefore(documentFragment, credit);
    document.body.appendChild(documentFragment);

I got good range walker suggestions in a separate post, but realized I asked the wrong question. I got an answer about ranges, but what I meant to ask about was a document fragment (or perhaps there's a way to set a range of the fragment? hrmmm). The walker provided was:

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");
});

That walker code is lifted from: http://stackoverflow.com/questions/2690122/remove-all-id-attributes-from-nodes-in-a-range-of-fragment

PLEASE No libraries (ie jQuery). I want to do this the raw way. Thanks in advance for your help
