execCommand with text and controls

[colinhumber]

I am using the execCommand method to apply bold, italics, and underline
formatting to text. There is no problem when only text is selected,
however, if a button control is selected by itself or as a part of some
text, I want to format the button text as well.

For example, if the text selected (including the control) is:

This is my <button id="123">text</button>.

and I select the entire string (or just the button control), I would
need the formatting tags to include the "text" inside the button tag as
well.

Any help would be fantastic.

Thanks in advance.
