Storing math equations from .doc MS Word file & restoring them

Question

I'm processing Microsoft Word files which contain math equations and images. I need to get these InlineShapes objects and store them as is & then restore them when needed.

I know how to get InlineShape objects from file, the problem is how can I store them. Saving them as images is not an option!
