Notepad++ Regex - patterns from Autonomy IDOL queries / Logs - regex

Question

I have a document which looks something like:
sort=SIZE:NumberDecreasing
FieldText=(((EQUAL{226742}:LocationId)) AND ())
FieldText=(((EQUAL{226742}:LocationId)) AND ((EQUAL{1}:LOD AND NOTEQUAL{1}:SCR AND EMPTY{}:RPDCITYID AND NOTEQUAL{1}:Industrial)))
FieldText=( NOT EQUAL{1}:ISSCHEME AND EQUAL{215629}:LocationId)
sort=DEALDATE:decreasing
From this I would like the word before a colon, and if there are {} brackets, before those too, a colon, and then the word after the colon. These should ideally be the only things left in the file, each on their own new line.
Output would then look like:
SIZE:NumberDecreasing
EQUAL:LocationId
EQUAL:LocationId
EQUAL:LOD
NOTEQUAL:SCR
EMPTY:RPDCITYID
NOTEQUAL:Industrial
EQUAL:ISSCHEME
EQUAL:LocationId
DEALDATE:decreasing
The closest I have come so far is:
Find:
^.?+ {[0-9]}:([a-zA-Z]+)
Replace with:
...\1:\2...
with the intent to run it several times, and later replace ... with \n
I can then remove multiple newlines.
Context: this is for a log analysis I am performing, I have already removed datestamps, and reduced elements of the query down to the sort and FieldText parameters
I do not have regular UNIX tools - I am working in a windows environment
The original log looks like:

The purpose of the whole exercise is to find out which fields are being queried and sorted upon (and how we are querying/sorting upon them) - to this end, the output could also usefully be distinct - although that is not essential.

Answer 1

The Perl program below is complete, and includes your sample data in the source. It produces exactly the output you describe, including reporting NOT EQUAL{1}:ISSCHEME as EQUAL:ISSCHEME because of the intermediate space.
use strict;
use warnings;
while (<DATA>) {
print "$1:$2\n" while /(\w+) (?: \{\d*\} )? : (\w+)/xg;
}
__DATA__
sort=SIZE:NumberDecreasing
FieldText=(((EQUAL{226742}:LocationId)) AND ())
FieldText=(((EQUAL{226742}:LocationId)) AND ((EQUAL{1}:LOD AND NOTEQUAL{1}:SCR AND EMPTY{}:RPDCITYID AND NOTEQUAL{1}:Industrial)))
FieldText=( NOT EQUAL{1}:ISSCHEME AND EQUAL{215629}:LocationId)
sort=DEALDATE:decreasing
OUTPUT
SIZE:NumberDecreasing
EQUAL:LocationId
EQUAL:LocationId
EQUAL:LOD
NOTEQUAL:SCR
EMPTY:RPDCITYID
NOTEQUAL:Industrial
EQUAL:ISSCHEME
EQUAL:LocationId
DEALDATE:decreasing
