Я пытаюсь проанализировать созданный мной XML-файл и извлечь из него информацию.Я изучаю этот учебник.Синтаксический анализ подключается к XML-файлу и оценивает первый тег, но впоследствии завершается сбоем, как показано в выходных данных.Ниже прилагаются схема XML-файла, код синтаксического анализа Java и вывод на консоль.
Есть идеи, почему он не читает следующий тег XML, и если да, что я должен изменить?
Файл XML:
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<filepath>/mnt/sdcard/Audio_Recorder/anonymous22242.3gp</filepath>
<filename>anonymous22242.3gp</filename>
<annotation>
<file>anonymous22242.3gp</file>
<timestamp>0:06</timestamp>
<note>test1</note>
</annotation>

<file>anonymous22242.3gp</file>
<timestamp>0:09</timestamp>
<note>lol</note>
</annotation>
<annotation>

Вывод:
