RegEx search/replace on CCK fields?

Is there any sort of tool that provides a nice interface to allow searching of CCK fields of all nodes matching some criteria, using RegEx for search/replace?

I have found the search and replace module, but that seems pretty basic in functionality at the moment and doesn't provide enough power to do what I would like to do.

A nice to have would also be a screen after the search is performed that shows you all the nodes that matched your search and let's you confirm you want to replace on each of them before you actually do the replace.
