Print text between delimiters IF it contains a certain term...
So I'm racking my brain on appropriate ways to solve a problem that once fixed, will solve every problem in my life. Its very easy (for you guys and gals) I'm sure, but I can't seem to wrap my mind around the right approach. I really want to use bash to do this, but I can't grasp how I'm going to do it. I have a pretty good handle on how to do it with a long regex in perl, but I'd rather not call that within bash, and I really don't want to add another perl script into the mix. As a sample of what I'm needing, here is some data;

Code:
-------------------------------
15:00:01.194213 IP 6.14.8.18.80 > 21.1.12.11.3311: tcp 183
-------------------------------
15:00:01.201435 IP 21.2.17.16.4918 > 6.15.2.18.80: tcp 0
-------------------------------
15:00:01.235586 IP 16.23.16.12.80 > 21.1.18.11.1519: tcp 141
Content-Type: application/ocsp-response
Content-Length: 3686
Connection: Keep-Alive
-------------------------------
15:00:01.235839 IP 16.25.36.42.80 > 21.1.18.11.119: tcp 1380
-------------------------------
15:00:01.235840 IP 6.235.16.12.80 > 21.1.18.121.1519: tcp 80
-------------------------------

The general idea is that I want to "search" a bit of text like this for certain terms, such as "Content-Length:" and receive the following as the result;

Code:
-------------------------------
15:00:01.235586 IP 16.23.16.12.80 > 21.1.18.11.1519: tcp 141
Content-Type: application/ocsp-response
Content-Length: 3686
Connection: Keep-Alive

So, what you have as the result is a match for the search text in question, as well all other information that falls within that packet's delimiters. Now obviously for small cases such as this, I could easily just do a grep -B 4 or something, but not only does that not work consistently, but it also will not get the end of that "section" before the next delimiter. I will graciously accept any solution but I prefer that it be in bash for my own curiousity and ease of implementation.

       tcp.h, tcp - definitions for the Internet Transmission Control Protocol (TCP)

SYNOPSIS

       #include <netinet/tcp.h>

DESCRIPTION

       The <netinet/tcp.h> header defines the following macro for use as a socket option at the IPPROTO_TCP level:

       TCP_NODELAY     Avoid coalescing of small segments.

       The macro is defined in the header. The implementation need not allow the value of the option to be set with setsockopt() or retrieved with
       getsockopt().
