Those are interesting ideas. We do have two such ideas for the near term, to be able to filter the nodes and resources by name. Xpath would be powerful but crm_mon is intended to be useful without any XML knowledge so I'd hesitate on that. Regular expressions are interesting though. What we're thinking is that crm_mon will take options to filter nodes and resources, and you can provide is either a single name, or a tag name, which will be looked up in the configuration. Tags are a "been there forever" feature in pacemaker but have not been used hardly at all. You can "tag" any nodes or resources, then you'd be able to use that tag name with crm_mon. It might be interesting to allow tags to match patterns and not just literal names.
