[j-nsp] apply-path regex for specific interface matching

[Ben Dale]

Dredging up an old thread here, but I have a requirement for an apply-path that matches ae* and ge-1/[01]/[0-4] unit * (for a prefix-list).

I must be missing something fundamental about the regex you can use in apply-path though, because all combinations I've tried seem to fail.

About as close as I can get to something that actually gives me results is "interfaces <[ae|ge-1/0/]*> unit <*> family net address <*>" which isn't all that useful.

It doesn't look like apply-path supports any nesting of regexes either eg: interfaces <[ae|ge-1/[01]/]*> returns no results at all

Any thoughts?
