Erstellen Sie Objekte aus dem DOM-parser in Java?

Können Sie eine POJO-Klasse zum speichern der Eigenschaften der station.

Diesem Programm BeanUtils zum Auffüllen der Eigenschaften in eine bean anstatt mit setter/getter für jede Eigenschaft.

Eine weitere Sache, die fehlt in deiner XML ist

<?xml version="1.0" encoding="UTF-8"?>

und schließen Sie alle station in einem äußeren stations tag wie unten dargestellt, um Valide XML, sagt

the root element must be well-formed

<?xml version="1.0" encoding="UTF-8"?>
<stations>
    <station>
        ...
    </station>

    <station>
        ...
    </station>
</stations>
