Replacing text nodes http://stackoverflow.com/a/1175796/391826 patched for MSIE

gistfile1.js

function htmlreplace(a, b, element) {    
    if (!element) element = document.body;    
    var nodes = element.childNodes;
    for (var n=0; n<nodes.length; n++) {
        // MSIE doesn't have Node
        if (nodes[n].nodeType == 3) {
            var r = new RegExp(a, 'gi');

            // MSIE8 and less doesn't have textContent
            if (nodes[n].textContent) {
              // If we assign try and assign a new value to
              // nodes[n].textContent
              // then 2011 bulds of MSIE9 crash with "A problem with this
              // website caused Internet Explorer to close"
              // (later builds are OK).
              // To be safe, assign to nodes[n].nodeValue instead.
              //nodes[n].textContent = nodes[n].textContent.replace(pattern, replacement);
              nodes[n].nodeValue = nodes[n].textContent.replace(r, b);
            } else {
              nodes[n].nodeValue = nodes[n].nodeValue.replace(r,b);
            }
        } else {
            htmlreplace(a, b, nodes[n]);
        }
    }
}

Thank you for taking an extra step to patch the script, I will be using this for my client websites.
