Does searching with regular expressions with a macro that uses xSearchDescriptor allow, in each instance found, to access the substrings associated with any backreferences (group 1, 2, etc.)?
It is certainly possible to do this with a second search performed on each instance found using xTextSearch, but it seems to me a repetition, even if only on a portion of text already filtered, of something that should already have been identified by the first search with xSearchDescriptor
