У меня есть фф. XML из URL:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<Phonebook>
<PhonebookEntry>
<firstname>Michael</firstname>
<lastname>De Leon</lastname>
<Address>5, Cat Street</Address>
</PhonebookEntry>
<PhonebookEntry>
<firstname>John</firstname>
<lastname>Smith</lastname>
<Address>6, Dog Street</Address>
</PhonebookEntry>
</Phonebook>
Я хочу отобразить оба значения PhonebookEntry (имя, фамилия, адрес). В настоящее время мой код отображает только запись в телефонной книге Джона Смита (последняя запись). Вот мой код.
