Reading kml file

Question

i download a KML file..Is there any way to use javascript/php to loop through the file and get all the coordinates in the KML file?

Thanks

Answer 1

You can use jquery ajax to read/loop the file. Just like normal XML.

Answer 2

If the KML file is of a decent size, then it could be very worthwhile to first convert it to JSON (in PHP) before sending it to the user's browser. JSON will produce a lower filesize and also be faster to parse (which could be of marginal benefit if the KML file is small, but very noticeable if it's complex).

// PHP:
$json = json_encode(simplexml_load_string($xml_string));
