Answer 1

Try using importNode:

/* Change these: */
var documentToCopy = document,
    iframeDocument = iframe.contentWindow.document;

/* Replace current document-element () with the new one: */
iframeDocument.replaceChild(
    iframeDocument.importNode(documentToCopy.documentElement, true),
    iframeDocument.documentElement
);
