Hi Craig, > 1. The HTMLEditorKit.ParserCallback takes a position with most of its > callback functions. Can this position be extracted from the HTMLTag's > elementBegin()?

How? Simple tags are those which dont come in XML like pairs. e.g. <BR> <META> will be simple tags. While <title> would be a start tag, as its got to have an end tag. Sadly, for every different case, we will need to manually handle them. > You mentioned you have started an implementation - if you have a > framework going, I'd be happy to continue with the donkey work.
