where to scrape ajax innerHTML?

Hm. Well it seems to me that their website is relying on that file to calculate the nearby ATMs. I don't think they're using a simple radius from the Zipcode center because when I search my old zipcode in the state of Kentucky, it shows a few results from way out in other states, since there aren't any nearby locations to KY.

My gut tells me that you'll likely have to rely on your own algorithm to get what you want out of that JS file. You could stick an extractor pattern on that JS file (as a scrapeableFile, of course) which saves the name of the location, the lon/lat, whatever info you need. The JS is saving it into an array, and I think you'll have to do the same.

If you write up your big extractor pattern, you can then make a script to run "After pattern is applied" (not after each pattern application) which processes your DataSet:

int numRecords = dataSet.getNumDataRecords();
int numVarsPerRecord = dataSet.getDataRecord(0).size();

String[][] branches = new String[numRecords][numVarsPerRecord];

for (int i = 0; i < numRecords; i++)
{
    // 'location' will be a Hashtable object, where each variable
    // from the extractor pattern is a key.
    location = dataSet.getDataRecord(i);

    // You know what the keys are, so just start yanking data out of
    // the 'location' variable and setting it in our array 'branches'
    branches[i][0] = location.get("NAME");
    branches[i][1] = location.get("URL");
    branches[i][2] = location.get("etc, etc...");
}

// Now you can process those entries however you want... by distance from its long/lat, etc.
// You could save this String[][] array into a session variable for later use if you want.

Really, it becomes up to you how you want to filter that array into desired results. Granted, this becomes your own algorithm, and not the one behind the curtain that they're using. *shrug*

Hope this is helping. If you want to try to get the array sorted right there in the script, you could import java.util.Arrays and then make a little class object which implements Comparator, so that you can use the following line of code:
    Arrays.sort(myComparatorClassObject, branches);
where 'myComparatorClassObject' is an instantiation of the custom class I just mentioned.

And, out of left field, you could choose to do this in a completely different programming language, like Python, whose capabilities are much more power and brief when it comes to scripting. (I personally don't like Java very much because it makes such basic tasks so amazingly complicated, when compared to other scripted languages.)

Either way you choose, it looks to me like you'll have to manually figure out a little radial distance thing to determine which results are closest to the zip code. If you can find the algorithm in the JS someplace, that's great, but otherwise, you could just hack one out to find the top 5 results by distance.
