The Data Tree View is a visual representation of an XML document and allows navigation of the Data by expanding out elements and generating XPath expressions.
XPath Data Model (XDM) uses a tree-structured model of the information content of an XML document.
The XPath expression for the current element is shown in the XPath navigation bar. Elements can also be navigated using the navigation buttons.
XSD (XML Schema Definition) is a recommendation of the World Wide Web Consortium (W3C) that specifies how to formally describe the elements in an Extensible Markup Language (XML) document.
