I'm doing the same, but with Hungarian licenses (where I live). I'm early in the process, currently creating an algorithm that reads the data from a 95% perfect scanned image so eventually I can move on to mobile captured photos.
My method here is to find the patterns in the one big returned string and just split it. It takes a lot of time, because my client asked for 99% accuracy even with those images.
I suppose your first clear the string out of things you don't need such as "AUTO DRIVER LICENSE" and just concentrate on extracting what you really need.
I know I didn't help much, I don't see an easy way to do this
