I am curious as to why you are trying to parse the block chain file instead of querying the coin daemon for the information

When I wrote the CCE 3 block explorer software, I completely abandoned the ABE style of parsing the block chain files as the daemon will give you all the information you need without having to adjust to the different block structures of various chains.

I might be willing to give you limited license to the CCE 3 database loader, if you would give me a better idea of what you are ultimately trying to do.
