Text parsing and substitution

Hi guys,

I am doing this module where I am gonna change the following sentence

"1:action=commit:user=joe:date=2005-02-02:"
"2:action=checkout:user=mark:date=2005-02-03:"

to something like
" 1. Commits by user Joe on date 2005-02-02 "
" 2. Checkouts by user Joe on date 2005-02-03"

making the above text a little bit more readable to the user. I started
of with a program which finds out the different key value pairs and
and based on the values append/create a string with approriate words
like

pseudocode only

parse the line,
load a hashmap with the key, value pairs
if(hash{action}=='commit') <---this is a mandatory field
string.="Commits"
if(defined hash{user})
string.="by hash{user})
if(defined hash{date})
string.="on date hash{date}"
...................................
...................................
if(hash{action}=='checkout') <---this is a mandatory field
string.="Commits"
if(defined hash{user})
string.="by hash{user})
if(defined hash{date})
string.="on date hash{date}"
..............................................
.............................................
I was thinking this sort of logic but a little apprehensive how elastic
it can be as I would be addressing so many actions and seperate if
blocks for all of them. Any suggestions or ideas on how to better
achieve what I want to do above.

cheers,
pop.
