I'm trying to get the latitude and longitude of a city with the Google Maps API and through PHP (SimpleXML).
I try to do it like this:
$xml = simplexml_load_file("http://maps.googleapis.com/maps/api/geocode/xml?address=Brussels,Belgium&sensor=false");
$lat= $xml->xpath("lat");
print_r($lat);
But this returns an empty array every time. Am I missing something?
Any help is much appreciated.
To search for a particular lat
do this:
<?php
$xml = simplexml_load_file("http://maps.googleapis.com/maps/api/geocode/xml?address=Brussels,Belgium&sensor=false");
$lat= $xml->xpath("/GeocodeResponse/result/geometry/location/lat");
print_r($lat);
?>
For all lat
occurrences specify the path of //lat
.
You should use this instead:
$xml->xpath("//lat");
In this way you're searching for lat tag which could be everywhere in the tree.
Your XPath query is wrong. It should be:
$lat= $xml->xpath("//lat");
The //
tells xPath to search for lat
nodes no matter where they are.
