Question

我有一个复杂的feed，我希望将XML文件的值回显到PHP表。

以下是英国RailDataFeed（Aka Darwin）的样本。

<?xml version="1.0" encoding="UTF-8"?>
<Pport xmlns="http://www.thalesgroup.com/rtti/PushPort/v12" xmlns:ns3="http://www.thalesgroup.com/rtti/PushPort/Forecasts/v2" ts="2018-01-01T21:58:48.2213864Z" version="12.0">
    <uR updateOrigin="Trust">
        <TS>
            <Location pta="21:59" ptd="21:59" tpl="ROBY" wta="21:59" wtd="21:59:30">
                <arr at="21:59" src="TRUST" srcInst="Auto" />
                <dep et="21:59" src="Darwin" />
                <plat conf="true" platsrc="A">4</plat>
            </Location>
            <Location pta="22:06" ptd="22:06" tpl="PRESCOT" wta="22:05:30" wtd="22:06">
                <arr et="22:06" src="Darwin" wet="22:05" />
                <dep et="22:06" src="Darwin" />
                <plat>1</plat>
            </Location>
        </TS>
    </uR>
</Pport>

我一直在努力和研究整天试图让回声发挥作用，但没有运气，我尝试了以下

测试（1）

$xml=simplexml_load_file("log.xml") or die("Error: Cannot create object");
echo $xml->Location[0]['tpl'] . "<br>";
echo $xml->Location[1]->arr['at']; 
echo $xml->Location[2]->dep['et']; 
echo $xml->Location[3]->plat;

测试（2）

$xml=simplexml_load_file("log.xml") or die("Error: Cannot create object");
foreach($xml->children() as $loc) { 
    echo $loc->Location['tpl'];
    echo $loc->arr['at'];
    echo $loc->plat;
    echo "<br>"; 
}

测试（3）

    $file = file_get_contents('log.xml');
echo $file;

仍然没有任何进展，在实现这一点后，我想将值添加到引导表中。

如果有任何想法请与我分享。

Answer 1

您可以通过attributes()方法访问属性值。另请注意，回显时会将值强制转换为字符串。

$str = <<<EOF
<?xml version="1.0" encoding="UTF-8"?>
<Pport xmlns="http://www.thalesgroup.com/rtti/PushPort/v12" xmlns:ns3="http://www.thalesgroup.com/rtti/PushPort/Forecasts/v2" ts="2018-01-01T21:58:48.2213864Z" version="12.0">
    <uR updateOrigin="Trust">
        <TS>
            <Location pta="21:59" ptd="21:59" tpl="ROBY" wta="21:59" wtd="21:59:30">
                <arr at="21:59" src="TRUST" srcInst="Auto" />
                <dep et="21:59" src="Darwin" />
                <plat conf="true" platsrc="A">4</plat>
            </Location>
            <Location pta="22:06" ptd="22:06" tpl="PRESCOT" wta="22:05:30" wtd="22:06">
                <arr at="22:06" src="Darwin" wet="22:05" />
                <dep et="22:06" src="Darwin" />
                <plat>1</plat>
            </Location>
        </TS>
    </uR>
</Pport>
EOF;

$xml = simplexml_load_string($str);

$c = 0;
foreach($xml->uR->TS->Location as $loc) {
    echo (++$c) . "\n";
    echo (string)$loc->attributes()['tpl'] . "\n";
    echo (string)$loc->arr->attributes()['at'] . "\n";
    echo (string)$loc->dep->attributes()['et'] . "\n\n";
}

Answer 2

@marekful回复后。

代码修改为

<?php

$str = file_get_contents('log.xml');
$xml = simplexml_load_string($str);
$c = 0;
foreach($xml->uR->TS->Location as $loc) 
{
    echo (++$c) . "\n";
    echo (string)$loc->attributes()['tpl'] . "\n";
    echo (string)$loc->arr->attributes()['at'] . "\n";
    echo (string)$loc->dep->attributes()['et'] . "\n\n";
    echo (string)$loc->plat . "\n\n\n";
}
?>

它与示例xml文件完美配合，但在添加原始XML文件后，它在文件本身中有多个标题，如下所示：

有办法：

忽略多个标头以避免错误。
将回显值发布到Bootstrap表。

干杯！
