我尝试使用PHP提取上面的xml，并尝试使用以下代码

$xml_response="my xml contents";
$xml = simplexml_load_string($xml_response);
echo $xml->person[0]['headers'] . "<br>";
echo $xml->id;

我可以获得id但我无法获得其他内容和

echo $xml->first-name;

它显示错误，因为-和first之间的name然后我有这么多类别的人详细信息如何创建循环以便检索？

Answer 1

要纠正已解析的XML的遍历，您必须将其视为对象。举几个例子：

$xml = simplexml_load_string($xml);
echo $xml->id . PHP_EOL;
echo $xml->educations->education[0]->{'school-name'} . PHP_EOL;
echo $xml->educations->education[0]->{'end-date'}->year . PHP_EOL;

注意：

标<something-with-something>必须由{'something-with-something'}表达式正确处理。

如果你想要迭代节点（这里是education）：

foreach($xml->educations->education as $item) { echo $item->{'school-name'} . PHP_EOL; echo $item->degree . PHP_EOL; }

如何使用PHP提取以下xml
