The structure of the source documents of an edited XQuery is displayed in a tree form in a view called the XQuery Input view. If the view is not displayed, it can be opened by selecting it from the Window > Show View menu. The tree nodes represent the elements of the documents.

You can use the XQuery Input view to drag and drop a node into the editing area to quickly insert XQuery expressions.
