Grep multiple search terms with context

I have a file that is a sort library in the format:

Code:
##def title1

content1
stuff1

content2
stuff2

##enddef
##def title2

etc..


I want to grep def and content and pull some trailing context from content

so the result would look something like:

Code:
##def title1
content2
stuff2
##def title2
content2
 stuff2
etc..

something like:

Code:
$ grep '##def|Content2 -A 1' ./file

where the -A 1 only applies to the second search term.

thoughts?

thanks.

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
