Using tidy for editing html

Hi,

Is it possible to use tidy for full editing of html?

What I want to do is to load a html file and be able to take 
elements and change their text, reorder them, add new ones and 
delete old ones (pretty much everything).

I am using the C++ binding and it only seems to have read 
functionality.
Is that an oversight or is there a design reason for it?

Essentially I want to know is there any inherent restriction in 
the design that would make adding functions like NewNode, 
CloneNode and RemoveNode to the C++ classes a bad idea?

        Thanks, Vin
