By using QT's DOM (QDom classes), if you do not need CSS.

(see QDomDocument::setContent)

You cannot. DOM is not defined for doing this.

However, what do you want to do with your <IMG> elements. Change them? If yes, 
try to use QDomDocument::elementsByTagName. (I suppose that KHTML has this 
function too, as it is a DOM function.)

If your problem is to save back the file to disk, then you should really use 
QDom (for example QDomDocument::toString or QDomDocument::save . These are 
*not* DOM functions.)
