Why do you have to use a regular expression?

Is all your other input pretty much identical in form?  Specifically, 
the number of interest is the last thing on the line, and always 
preceded by a colon?

What does "trim down" mean?  Do you need something out of the string, or 
are you just discarding/ignoring it?

s = '"DcaVer"=dword:00000640'
value = int(s.split(':')[-1], 16)

(In other words, split on colons, take the last field and, treating it 
as a hex value, convert to an integer.)
