Get whatever it is you are using to parse your KML to build you some
array of the Placemarks you are interested in. Storing the API marker
objects created from the Placemarks might be useful, rather than the
KML itself, as that makes it easy to get lat/long in a useful form.
When you want to check through the array, simply
for ( key in myArray) {
// do something with each object myArray[key]
// and test for distance from target
// and do something else if distance is ok
}
I'm not going to write your code for you, but if you make a start
people will help you out if you hit problems as you work through the
job.
