使用来自URL php的属性提取XML数据

Question

我有一个响应XML数据的网址 像这样

<Account account="ihs" timezone="GMT+05:30">
<Description>The Indian Heights School</Description>
<Device id="09647">
<Description>DL1PD0228</Description>
<EventData device="09647">
<Timestamp epoch="1416968997">2014/11/26 07:59:57 GMT+05:30</Timestamp>
<StatusCode code="0xF401">Ignition_On</StatusCode>
<GPSPoint>28.56262,77.05264</GPSPoint>

我想使用php从xml中提取所有<Description> tage 请帮帮我

我也在使用curl, simplexmlloadfile, simplexmlloadstring 我这样做

 $ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);    // get the url contents

$data = curl_exec($ch); // execute curl request
curl_close($ch);

$xml = simplexml_load_string($data);
print_r($xml)

我得到了

                        )

                )

在描述前面我注意到并且不知道如何提取它

Answer 1

你需要保持敏感：

echo $xml->Description;

也是一个foreach：

foreach($xml->device as $device) {
    echo $device->Description;
}
