I created a free XML viewer applet that runs in the Applet Runner plug-in for IntelliJ IDEA and other JetBrains IDE such as Android Studio.
You can open files, paste xml from clipboard, browse the XML in a tree structure, navigate/copy/paste the breadcrumbs.
To run it, download the free Applet Runner plugin from JetBrains marketplace and execute the free XML viewer located at https://www.japplis.com/tree-data-explorer/online/xml-viewer.html.
