我正在解析google map api以获取latlong表单地址 . 我成功获得了xml . 如何从xml响应中获取latlong .

我的回答是

SimpleXMLElement对象（[status] =>确定[result] => SimpleXMLElement对象（[type] =>数组（[0] => locality [1] =>政治）[formatted_address] =>新德里，德里，印度[address_component ] =>数组（[0] => SimpleXMLElement对象（[long_name] =>新德里[short_name] =>新德里[type] =>数组（[0] => locality [1] =>政治））[1 ] => SimpleXMLElement对象（[long_name] => West Delhi [short_name] => West Delhi [type] => Array（[0] => administrative_area_level_2 [1] =>政治））[2] => SimpleXMLElement对象（[ long_name] =>德里[short_name] => DL [type] =>数组（[0] => administrative_area_level_1 [1] =>政治））[3] => SimpleXMLElement对象（[long_name] => India [short_name] = > IN [type] => Array（[0] => country [1] => political）））[geometry] => SimpleXMLElement对象（[location] => SimpleXMLElement对象（[lat] => 28.6353080 [lng] = > 77.2249600）[location_type] => APPROXIMATE [viewport] => SimpleXMLElement对象（[southwest] => SimpleXMLEl ement对象（[lat] => 28.4010669 [lng] => 76.8396999）[northeast] => SimpleXMLElement对象（[lat] => 28.8898159 [lng] => 77.3418146））[bounds] => SimpleXMLElement对象（[southwest] = > SimpleXMLElement对象（[lat] => 28.4010669 [lng] => 76.8396999）[northeast] => SimpleXMLElement对象（[lat] => 28.8898159 [lng] => 77.3418146）））））

    使用DOM XPath更容易，DOMXpath :: evaluate（）方法可以从xml中获取标量值：

    $xml = <<<'XML'
<GeocodeResponse>
 <status>OK</status>
 <result>
  <geometry>
   <location>
    <lat>37.4217550</lat>
    <lng>-122.0846330</lng>
   </location>
   <location_type>ROOFTOP</location_type>
   <viewport>
    <southwest>
     <lat>37.4188514</lat>
     <lng>-122.0874526</lng>
    </southwest>
    <northeast>
     <lat>37.4251466</lat>
     <lng>-122.0811574</lng>
    </northeast>
   </viewport>
  </geometry>
 </result>
</GeocodeResponse>
XML;

$dom = new DOMDocument();
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);

$lat = $xpath->evaluate('number(/GeocodeResponse/result/geometry/location/lat)');
$lng = $xpath->evaluate('number(/GeocodeResponse/result/geometry/location/lng)');

var_dump($lat, $lng);

    输出：

    float(37.421755)
float(-122.084633)
