Как получить правильный результат. Ява
This Java file is suppose to run and pull the information from the legoSets.XML and show me the output. Right now the output I am getting is sum-num only. it does not display any information of the other 3 i need to see. (name, year, num-parts) I have comment out set-num to see if i can get name to put out results but it still only shows set-num.
---Desired Output---
<set-num>00-1</set-num>
<name>WEETABIX CASTLE</name>
<year>1970</year>
<num-parts>471</num-parts>>
But My output shows only the set-num
---real output---
1: 00-1
2: 0011-2
3: 0011-3
4: 0012-1
5: 0013-1

Что я уже пробовал:
измените порядок что то.Java-файлы загружаются из XML. попробовал какое-то онлайн-решение.
