用于回显PHP的XML字符串

我有一个复杂的提要，希望将XML文件的值回显到PHP表中

以下是英国RailDataFeed（又名Darwin）的示例

仍然没有任何进展，在实现这一点之后，我也想将这些值添加到引导表中

---

如果有任何想法，请与我分享。

您可以通过该方法访问属性值。另外，请注意，值在回显时转换为字符串

$str = <<<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";
}

$str=位置为$loc）{
回显（+$c）。“\n”；
echo（字符串）$loc->attributes（）['tpl']。“\n”；
echo（字符串）$loc->arr->attributes（）['at']。“\n”；
echo（字符串）$loc->dep->attributes（）['et']。“\n\n”；
}

在@marekful回复之后

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";
}
?>

uR->TS->位置为$loc）
{
回显（+$c）。“\n”；
echo（字符串）$loc->attributes（）['tpl']。“\n”；
echo（字符串）$loc->arr->attributes（）['at']。“\n”；
echo（字符串）$loc->dep->attributes（）['et']。“\n\n”；
回显（字符串）$loc->plat。“\n\n\n”；
}
?>

它可以很好地处理示例xml文件，但在添加原始xml文件后，文件本身有多个头，如下所示：

有没有办法：

忽略多个标题以避免错误

将回显值发布到引导表

---

干杯

$xml->Pport->uR->TS->Location[0]

关于4MB大的xml源文件，我还有一个问题。文件内部包含多个标题，是否有办法忽略标题，使其不会显示任何错误。只有在使用不同的名称空间时，普通属性才不需要

->attributes（）

。您可以只编写

（字符串）$loc['tpl']

，而不是

（字符串）$loc['tpl']

。不，多个标记无效。您需要单独处理它们，并在PHP代码中组合结果。欢迎使用！如果我的答案有助于您获得XML属性，请随意投票并接受我的答案。请不要在评论或答案中发布其他问题；本网站的格式是围绕每个页面构建的，页面顶部有一个问题，下面有该问题的答案。如果尚未阅读，则可能需要通读中的和其他页面。
