OK; that is indeed rather messy; especially since *all* of those
renewcommands are quite redundant to LaTeX2HTML...

...well, sort of.

The HTML <OL> ordered list does not use brackets around its numbers.
If you really *do* want that style of numbering, you have to use
a <DL> description list, and provide the numbering yourself.

LaTeX2HTML does this in certain circumstances.

However, for simplicity, I suspect that getting:

<OL TYPE="1">

would be quite acceptable here.  Agreed ?

BTW, you could probably use a stylesheet to make the above HTML
appear onscreen with parenthetical numbering; but that's really
a different issue.

If the format of the output is always as you described, then an appropriate
reg-exp could indeed be inserted to cause all those redefinitions to be
filtered-out or ignored.

Alternatively, can the tool be customised to produce output as follows ?

\item Item1

This would give an immediate solution to all your problems,
and would work as expected in both LaTeX and LaTeX2HTML.

Hope this helps,
