Extract portion of text - IRC Log


Hello,

I have a lot of files containing chat-log (IRC) and would like to extract information out of these files.

File sample
Code:
Session Start: Sat Apr 03 15:06:29 2010
Session Ident: XXX
[15:06] XXX is ~X@host-85-85-85-154.isp.be * XXX
[15:06] XXX on #channel1 #channel2 #channel3 
[15:06] XXX using *.undernet.org The Undernet Underworld
[15:06] XXX End of /WHOIS list.
-
[15:06] <Me> Hello
[15:07] <Me> How are you ?
[15:15] <Me> Bye
Session Close: Sat Apr 03 15:16:52 2010

Session Start: Sat Apr 03 15:47:53 2010
Session Ident: XXX
[16:21] XXX No such nick
[16:21] XXX End of /WHOIS list.
-
[16:30] <Me> Hello
[16:31] <Me> How are you ?
[16:32] <XXX> Hello, fine and you ?
[16:32] <Me> ....
Session Close: Sat Apr 03 17:21:35 2010
I would like to extract in a separate file the info between the 'Session Start' and the 'Session Close' and isolate the /WHOIS informations at top of bottom of conversation like

File1
Code:
Session Start: Sat Apr 03 15:06:29 2010
Session Ident: XXX
[15:06] <Me> Hello
[15:07] <Me> How are you ?
[15:15] <Me> Bye
Session Close: Sat Apr 03 15:16:52 2010

[15:06] XXX is ~X@host-85-85-85-154.isp.be * XXX
[15:06] XXX on #channel1 #channel2 #channel3 
[15:06] XXX using *.undernet.org The Undernet Underworld
[15:06] XXX End of /WHOIS list.
File 2
Code:
Session Start: Sat Apr 03 15:47:53 2010
Session Ident: XXX
[16:30] <Me> Hello
[16:31] <Me> How are you ?
[16:32] <XXX> Hello, fine and you ?
[16:32] <Me> ....
Session Close: Sat Apr 03 17:21:35 2010

[16:21] XXX No such nick
[16:21] XXX End of /WHOIS list.
I can find the interesting lines with egrep commands but don't see how to extract info and put it correctly into separate files ...

Any help is welcome. Thanks.

Well its only a quick knock up, but you get the idea:
Code:
awk 'BEGIN{i=1}/Start/,/Close/{if($2 == "XXX")whois = (whois?whois:"")"\n"$0;else if(!/-/)print > "FILE"i}/Close/{print whois > "FILE"i++;whois=""}' file

Thanks it's working great and I can integrate it into a script and found the way to handle the case with $2.
