我有一个xml提要,需要从中访问元素。然而,我尝试过的方法都没有奏效。
以下是完整的xml提要:
<GeocodeResponse>
<status>OK</status>
<result>
<type>locality</type>
<type>political</type>
<formatted_address>Liverpool, Merseyside, UK</formatted_address>
<address_component>
<long_name>Liverpool</long_name>
<short_name>Liverpool</short_name>
<type>locality</type>
<type>political</type>
</address_component>
<address_component>
<long_name>Merseyside</long_name>
<short_name>Mersyd</short_name>
<type>administrative_area_level_2</type>
<type>political</type>
</address_component>
<address_component>
<long_name>England</long_name>
<short_name>England</short_name>
<type>administrative_area_level_1</type>
<type>political</type>
</address_component>
<address_component>
<long_name>United Kingdom</long_name>
<short_name>GB</short_name>
<type>country</type>
<type>political</type>
</address_component>
<geometry>
<location>
<lat>53.4115400</lat>
<lng>-2.9901160</lng>

</southwest>

</result>
</GeocodeResponse>
我试图选择几何体->位置->纬度->位置,然后在这个纬度和lng内。
您尝试过simplexml_load_string或simplexml_lad_file吗?只需加载数据,然后访问您想要的节点,如下所示:
$xml = simplexml_load_file('your.xml');
echo $xml->GeocodeResponse->result->geometry->location->lat;
echo $xml->GeocodeResponse->result->geometry->location->lon;
如果你有一个字符串,你可以做:
$str = "<?xml version='1.0'?>
<document>
<cmd>login</cmd>
<login>Richard</login>
</document>";
$xml = simplexml_load_string($str);
print_r($xml);
print_r($xml->document->cmd);
// Remember to type cast it a string if you want the actual value.
// Example:
$myval = (string) $xml->document->cmd;
