我正在嘗試讀取我創建的XML文件。我正在使用此代碼,但除了'文件已成功加載'以外沒有任何內容。我試過xpath和其他許多,但它只是不輸出。我的XML可能有問題,因爲我手工創建了該文件,而且以前從未創建過XML文件。PHP SimpleXML不輸出任何內容
最終,我的目標是能夠讀取擴展屬性並獲取描述,類和圖標。
<?php
if(!$xml = simplexml_load_file('formats.xml')) {
echo 'the file was loaded successfully';
print_r($xml);
}
else {
echo 'the file was not loaded';
}
?>
這裏是XML:

您的XML無效 - 它沒有一個根元素。由於''包含其他元素,因此它不應該是自封閉的('/>'在開始標記結束時) –
您的邏輯是反向的 - 您輸出消息說明文件在'!$ xml'加載成功時,這意味着它實際上失敗了,因爲前面提到了無效的XML。 –
檢查['libxml_get_errors()'](http://php.net/manual/en/simplexml.examples-errors.php)以查看SimpleXML在抱怨什麼。 –
