How do you scrabble the rest of its functions, Like Experience bar is on the Left along with the Portrait and its Stub, Hero Icon on the right along with Minimap and Attributes below the Experience Bar?
For you, I would suggest using the trigger action "Hookup Standard Dialog Item" to get these interface elements as trigger dialog items. Then you can manipulate them using all the other dialog item actions.
SC2Layout files are a bit more involved and you will need more of a foundation in them before trying this.
I believe one example of a name would be "UIContainer/ConsoleUIContainer/InfoPanel/InfoPaneHero/ExperienceBar". This particular element has a type of Progress Bar.
Once you've used Hookup Standard Dialog Item on that path, you can save the result to a dialog item variable using Last Created Dialog Item, and perform any moves or other operations on it that you want.
