regex question

[Rajarshi Guha]

Hi,
  this is not specifically a Python question but since I'm doing it in
Python I thought I'd ask here.

I have a BibTeX file with entries of the form

@Article{dkapp3,
  author = 	 {Kier, L.B},
  title = 	 {Distinguishing Atom Differences in a Molecular Graph Index},
  journal = 	 {Quant. Struct.-Act. Relat. Pharmacol.,Chem. Bio},
  year = 	 {1986},
  OPTkey = 	 {},
  volume = 	 {5},
  OPTnumber = 	 {},
  pages = 	 {7-12},
  OPTmonth = 	 {},
  OPTnote = 	 {},
  OPTannote = 	 {}
}

(it also has entries for Book and InBook)

I have an re that is able to get each bibitem: @Article{(.*?)}\n
>From the result I can easily get the key using: @.+?\{(.+?),

I was wondering if it would be possible to do the two things in one re.
That is, first get the string of 1 bibitem and then within that get the
key from the matched bibitem. 

I think I should be using a lookbehind(?) but I'm not sure.

Any pointers would be appreicated

Thanks
