使用SimpleXML解析/读取XML

Question

我尝试使用simplexml读取/解析XML。问题是它没有返回任何结果。我怀疑错误将出现在foreach声明的某处。有谁有想法吗？我将非常感激！

PHP：

$xml = file_get_contents("test.xml");
$feed = simplexml_load_string($xml);
$namespaces = $feed->getNamespaces(true);
print_r($namespaces);
foreach($feed->children($namespaces['ord']) as $child) {
    $orde = $child->orderHeader;
    $order = $orde->orderType;
    print_r($order);
}

XML：

Answer 1

1）你有一个缺失的数据：最后是dataPack。

2）您有多个名称空间，并试图像访问它一样进行访问。

修复结束标记后，删除dat：datapack和dat：datapackItem，它将起作用。

要了解如何让多个命名空间工作，请检查此＆gt; parse an XML with SimpleXML which has multiple namespaces
