The Outline view displays a general tag overview of the currently edited XML Document. It also shows the correct hierarchical dependencies between elements. This makes it easier for you to be aware of the document structure and the way element tags are nested. It allows for fast navigation of the document by displaying the start of the content of the child elements in the node of the parent element, thus allowing you to quickly see the content of an element without expanding it in the Outline tree. It also allows you to insert or delete nodes using contextual menu actions.
By default it is displayed on screen, but if you closed it you can reopen it from .
The upper part of the Outline view contains a filter box that allows you to focus on the relevant components. Type a text fragment in the filter box and only the components that match it are presented. For advanced usage you can use wildcard characters (*, ?) and separate multiple patterns with commas.
It also includes a 
Settings menu in the top-right corner that presents a variety of
options to help you filter the view even further.
