Decoding log files in binary using an XML file.

[captainfantastic]

I found a library that might fit the bill, PyXML or easeXML seem like they might be able to achieve what I am looking for.

looking at the input and the structure of the message and the structure of the xml that decodes it the lengths quoted dont seem to match up:

Message:

Output:

I feel like im missing something obvious here but the message is 80 bytes and the length is listed as 40(DEC) or 64(HEX)
