Doesn't seem to work on localizable strings

[nicholaslie90]

Hi @roana0229, I'd like to thank you for your time to make this awesome plugin. However, upon my testing, it doesn't seem to work on localizable strings (strings-in.xml, strings-de.xml, etc) and only works on strings.xml. When I try to reformat the file, I got the following error.

Here's the stacktrace:
null java.lang.NullPointerException at XmlSorterAction$NodeComparator.compare(XmlSorterAction.java:129) at XmlSorterAction$NodeComparator.compare(XmlSorterAction.java:119) at java.util.TimSort.countRunAndMakeAscending(TimSort.java:355) at java.util.TimSort.sort(TimSort.java:234) at java.util.Arrays.sort(Arrays.java:1512) at java.util.ArrayList.sort(ArrayList.java:1454) at java.util.Collections.sort(Collections.java:175) at XmlSorterAction.actionPerformed(XmlSorterAction.java:70) at com.intellij.openapi.keymap.impl.IdeKeyEventDispatcher$3.performAction(IdeKeyEventDispatcher.java:595) at com.intellij.openapi.keymap.impl.IdeKeyEventDispatcher.processAction(IdeKeyEventDispatcher.java:646) at com.intellij.openapi.keymap.impl.IdeKeyEventDispatcher.inInitState(IdeKeyEventDispatcher.java:485) at com.intellij.openapi.keymap.impl.IdeKeyEventDispatcher.dispatchKeyEvent(IdeKeyEventDispatcher.java:215) at com.intellij.ide.IdeEventQueue._dispatchEvent(IdeEventQueue.java:631) at com.intellij.ide.IdeEventQueue.dispatchEvent(IdeEventQueue.java:386) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:116) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:105) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:82)

Oh man, it turns out I got a malformed XML. Everything's good!
