Finished script: Use grep find/change to fill in a supplied table of contents

Question

This script is now complete, and has been the subject of most of my previous posts. Just in case anyone wanted to know what the finished script ended as, here it is.
Thanks so much to all. A lot of really helpful folks on this board are very responsible for the success of this task. This script is to be one of hopefully many in the creation of our records. But it's a huge leap forward. Thanks again to everyone that helped.
Cheers,

Task:
Automatically find town names in listings, and fill in table of contents template on page 2 accordingly.
Example of page 2 toc, initially:
Example of a page of content. The town names are what need to be referenced on the TOC:
Example of page 2 toc once script is finished:
Because of the need to include the transaction dates on the TOC (comes as a provided, tagged-text file), a simple Indesign-generated TOC can't be used alone.
This script uses an Indesign-generated TOC that's on a master page called "T-tocGen" ... It then uses grep search and replaces to grab the needed information, and insert it into the page 2 TOC.
The script will update a generated TOC and then search for an instance of a page number, and town name. The generated toc lists all included towns in the following format:
(line start)## tab townName(line end)
In Grep, this would be (please note, extra \ for \d and \t ... javascript needs that for some reason):
^\\d+\\t(.*)$
After the script gets the info it needs from a found instance of the above, it replaces that line with "---", to prevent that line from being picked up once again.
The script with then place the needed page number in it's rightful place on page 2, replacing the XX.
A while loop is used to repeat the above process until there are no longer any instances of "^\\d+\\t(.*)$" present.
Not every town runs every issue, so once the script is done, it removes all remaining instance of "XX" on the page 2 TOC.
FINAL CODE:
TOC replace
This script will use grep find/change methods to apply page numbers in
tocGen to the XX's on page2TOC.
// define the text frame of generated TOC
    var tocGenFrame  = document.masterSpreads.item("T-tocGen").pages.item(0).textFrames.item(0);
// udpate generated TOC ... store contents in tocGenStuff
    var tocGenStuff = updateTOCGen();
// set variable for while loop
var okGo = "1";
// while okGo isn't 0
while(okGo.length!=0)
// get town info from tocGen
getCurrentTown();
// replace XX's with tocGen info
replaceTown();
// grep find ... any remaining towns with page numbers in tocGen?
app.findGrepPreferences = app.changeGrepPreferences = null;
app.findGrepPreferences.findWhat = "^\\d+\\t(.*)$";

// store grep results content into currentLine
currentLine = currentGen[0].contents;
// match to get array of grep found items
currentMatch = currentGen[0].contents.match("^\\d+\\t(.*)$");
// second found item is town name, store as currentTown
currentTown = currentMatch[1];
// change current line to --- now that data has been grabbed
// this is because loop will continue as long as the above grep find yields a result
       app.findGrepPreferences.findWhat = "^\\d+\\t"+currentTown+"$";
              app.changeGrepPreferences.changeTo = "---";

    app.findGrepPreferences.findWhat = "^XX\\t"+currentTown+" \\(";
    app.changeGrepPreferences.changeTo = currentLine+" \(";
app.activeDocument.changeGrep();   
function updateTOCGen()
//set vars ... toc text frame, toc master pag
    var tocGen  = document.masterSpreads.item("T-tocGen").pages.item(0).textFrames.item(0);
    var tocGenPage  = document.masterSpreads.item("T-tocGen").pages.item(0);
//SELECT the text frame generatedTOC on the master TOC
    tocGen.select();
//Update Table of Contents by script menu action:
    app.scriptMenuActions.itemByID(71442).invoke();
//Deselect selection of text frame holding your TOC:
    app.select(null);
//store contents of toc text frame in variable
    var tocGenText = tocGen.contents;
//return contents of tocGen
    return tocGenText;

Thanks for the reply.
You are correct but the problem is there are three rows, One row is 100% black, the second is 60% black and the third is 40% black. I want to change the black to blue, the 60% black to an orange and the 40% black to a light shaded blue. In the find/change option you can select the tint you want to find and replace but yea.. does work on table cells.. oddly enough.
