Currently your page is failing here:
data_1234[i] = markers[i].getAttribute("num");
Because i == 2 and you only have two markers in your xml (marker[0]
and marker[1])
I don't understand why you have all the i++ sprinkled inside the for
(var i = 0; ...) loop.
Get it working for one xml file, then extend it to multiple routes in
the same file or multiple xml files.
