Thanks for the information below.
Just one more question: at the end of the search can I have two different
endings (i.e. <roman> and [return]). Or just do the search manually?

Find and replace will do this. Display the Find and Replace dialog. Click
More to display the full dialog. Check the 'Use wildcards' checkbox.
Search for: \<bold\>(*)\<roman\>
Replace with: \1
With the cursor in the Replace box click the format button and select Font >
Bold.
Similarly for italic.
