Manipulate iframe DOM

I dunno know if this is IE bug or not but suppose you want to insert more nodes into nodes which belong to iframeDom using functions like appendChild and insertBefore.

In that case you should not do node.appendChild(document.createTextNode());
This will fail as document.createTextNode belongs to main document and not iframe document. Instead what you need to do is

node.appendChild(node.ownerDocument.createTextNode());
