John Resig exploring the insertAdjancedHTML method included in Internet Explorer and Opera browsers. He writes:

While looking for improvements to injecting HTML fragments into a document (which I mentioned, in passing, when I looked at using Document Fragments) I decided to spend some more time with Internet Explorer's insertAdjacentHTML method.

This method has been in Internet Explorer since version 4.0 - as well as is in the current release of Opera - and allows you to inject fragments of well-formed HTML into a variety of locations in a document.
