phpの単純なxmlオブジェクトで問題が発生しています。
ログに次のxmlデータがあります
SimpleXMLElement Object
(
[@attributes] => Array
(
[title] => test
[scanner] => Data
[id] => WordData
[position] => 1800
[error] => false

[subpod] => Array

.....more simpleXmlElement object

私のphp変数です$xmlObj = SimpleXMLElement Objectが、私が次のものを持っているとき
if (is_array($xmlObj->subpod)){
echo 'is array';
}else {
echo 'not array';
}
出力は常に「配列ではありません」であり、コードをエコーさせたい「配列です」
$xmlObj->subpod配列だと思いました。テスト$xmlObj->subpod[0]->plaintextすると、実際には文字列が返されます。この問題を解決する方法がわかりません。誰か助けてもらえますか？
