Help with awk (making simple/advanced ini parser)

Hello

I'm searching some kind of example (or ready-made solution, but I don't really want it, because I want to learn awk more), to make something like a parser in awk for something like this (I put example, because I don't really know how to explain this):
Code:
[something]
line1=1
line2=0
line3=1
line4=1

[something]
line1=1
line2=0
line3=5
line4=1

[something]
line1=1
line2=0
line3=2
line4=1

[something]
line1=1
line2=0
line3=5
line4=15

And I want to have output like this:
Code:
[something]
line1=1
line2=0
line3=5
line4=1

[something]
line1=1
line2=0
line3=5
line4=15

I mean... I want to export from one file whole lines from "[something]" to "\n" which have line3=5
I have to notice, that lines aren't in same amount, for example there can be:
Code:
[something]
line1=1
line2=0
line3=5
line4=15

But can be also:
Code:
[something]
line1=1
line2=0
line3=5
line4=15
line5=1
line6=6

etc.

Is it possible to made? And sorry for my english, I'm still learning Smilie

Hope, that you will understand me.

NAME
English - use nice English (or awk) names for ugly punctuation variables SYNOPSIS
use English; use English qw( -no_match_vars ) ; # Avoids regex performance penalty # in perl 5.16 and earlier ... if ($ERRNO =~ /denied/) { ... } DESCRIPTION
This module provides aliases for the built-in variables whose names no one seems to like to read. Variables with side-effects which get triggered just by accessing them (like $0) will still be affected. For those variables that have an awk version, both long and short English alternatives are provided. For example, the $/ variable can be referred to either $RS or $INPUT_RECORD_SEPARATOR if you are using the English module. See perlvar for a complete list of these. PERFORMANCE
NOTE: This was fixed in perl 5.20. Mentioning these three variables no longer makes a speed difference. This section still applies if your code is to run on perl 5.18 or earlier. This module can provoke sizeable inefficiencies for regular expressions, due to unfortunate implementation details. If performance matters in your application and you don't need $PREMATCH, $MATCH, or $POSTMATCH, try doing use English qw( -no_match_vars ) ; . It is especially important to do this in modules to avoid penalizing all applications which use them. perl v5.18.2 2014-01-06 English(3pm)
