Take some pictures of the damage and culprit's door. Confront her and get her to pay for the damage. If she doesn't want to own up to her negligence. Call your insurance company and get their advice on if a claim can be made where they'll go after her for the damages. I'm pretty sure you've got a good case against her for the damages. File with your own insurance and have them go after the bills from her insurance. Good luck.

*edit* Make sure you take pictures of how the cars are parked next to one another. So you can prove your case that the arrangement of the damage and culprit's car coincide.
