Need support on "universal-xml-plugin"

Hi,

I found this plugin “universal xml plugin” which is support identifying element on both android and ios, the link is appium/packages/universal-xml-plugin at master · appium/appium · GitHub
During my researching, i couldn’t found any article or example related to this so that i coudn’t understand more and apply in my project. My concerns are how to config, identify element in xml, how to use in .java file, and how to execute …

Can someone help to share any article/example project so that i can have clearly understanding about this plugin and apply in my project. Thanks in advance

In case of any idea, please kindly let me know.
