you have to give some more detail of what you want to achieve.
are you talking about a visualization or just text mode/scripting
info? the vmd selection language allows you very flexible selections
of atoms, you just have to combine them with "and" and "or" and
you can probably construct something based on that.
alternately, you can check the list of h-bond donors and h-bond
acceptors for multiple entries of the same atom index.
cheers,
axel.
