我希望有人可以帮助我做一件简单的事情，但我有点挣扎。我有一个具有以下结构的 XML 文件...

我正在使用以下 PHP 代码来解析这个巨大的 XML 文件...

<?php
error_reporting(E_ALL);
ini_set( 'display_errors','1');
libxml_use_internal_errors(true);
libxml_clear_errors();

// create the reader object
$reader = new XMLReader();

// reader the XML file.
$reader->open('/home/hingeweb/www/tintworld/magmi/integration/scripts/worldpak-small.xml');

// Move to the first "[App name]" node in the file.
while ($reader->read() && $reader->name !== "App");
// Now that we're at the right depth, hop to the next "[App name]" until the end of tree/file.
while ($reader->name === "App") {
  $node = new SimpleXMLElement($reader->readOuterXML());

  // *** Do something of interest with $node, this is the App we have been looking for. ***
  // Skip to the next node of interest.
  $reader->next("App");
}

//foreach ($data as $key => $value) {
//  echo "Key: $key; Value: $value<br />\n";
//}

echo "Finished Processing... \n \n";

?>

我正在尝试将其中一些结果设置为数组。例如，我很想将 $data->PartNumber 放入一个数组中，这样我就可以对结果进行内爆并将其导入 SQL。我不想导入 XML 文件的所有字段，所以我想我必须单独编码这些字段。

是否有人可以为我指出正确的方向来做到这一点？

谢谢！
