Print all lines between pattern where any line matches second pattern

Question

I have an email log file like this:

2013-09-11 12:02:08  INFO: ------------------------------
2013-09-11 12:02:08  INFO: Javamail session sending email
2013-09-11 12:02:08  INFO: Session properties: 
2013-09-11 12:02:08  INFO:    com.hof.email.starttime=20130911120208
2013-09-11 12:02:08  INFO:    mail.smtp.auth=true
2013-09-11 12:02:08  INFO:    mail.smtp.connectiontimeout=60000

2013-09-11 12:02:08  INFO: Subject: Your Report Data
2013-09-11 12:02:08  INFO: Message ID: <id>
2013-09-11 12:02:09  INFO: Email sent successfully
2013-09-11 12:02:09  INFO: Javamail session ended
2013-09-11 12:02:09  INFO: ------------------------------

What I need to do is print this entire record if the email subject matches a particular string.

That is, what I think I'd like to do is, when Subject = 'Your Report Data', then print all lines between and including the n-1th occurrence of '------------------------------' and the 1st occurrence of '------------------------------' from the Subject match.

Answer 1

if the part between the lines is always the same, you can use grep with -A and -B.

Answer 2

This only works with gawk

awk '/Subject: Your Report Data/{printf "%s%s\n",$0,RT}' RS="------------------------------" file

Edit: a more complex version, prints correct section

cat file
