Weird search and replace

I'm trying to do a search-and-replace for a certain string (#1) from a bigger string (#2), take that string (#1), do an SQL search, then do a little fiddling to make another string (#3), and put that string (#3) back into the big string (#2) to replace the certain string (#1). Here's what I need. I have a string such as this: "Yadda yadda yadda yadda '32'(l) yadda yadda yadda '2'(l) yadda '419'(l)." (#2) I need to find the strings like '32'(l), '2'(l), and '419'(l), including the single quotes. Basically a '[0-9]*'(l). This is #1. Take that string, look up a record in an SQL table based on the number in the single quotes. Take a field in the record (#3) and replace #1 with it. So basically, we have: "Yadda yadda yadda yadda supplanted-string yadda yadda yadda supplanted-string yadda supplanted-string." (#2) I really hope I'm explaining this properly, and after a few attempts, I have no clue where to restart. Does anyone have any ideas how to do this?
