Carefully check your dataset to ensure that this problem hasn't already been handled for you.

I spent a fair amount of time first creating a taxonomy of probably street name ending, using regexp conditionals to try to pluck out the street number from the full address strings and everything and it turned out that the attributes table for my shapefiles had already segmented out these components.

Before you go forward with the process of parsing address strings, which is always a bit of a chore due to the inevitably strange variations (some parcel addresses are for landlocked parcels and have weird addresses, etc), make sure your dataset hasn't already done this for you!!!
