In the example above, "studentsList" is the root element. The topmost element is called the "root" element, and contains all other elements, which are called "child" elements. In an XML file, elements are arranged in a hierarchy, which means that elements can contain other elements. XML HierarchyĮach instance of an XML tag is called an element. Tags aren’t supposed to be seen by users, only the software itself. Each tag represents a type of data, like "first name," "last name," or "score," and tells the computer what to do with the plain text data inside of it. While plain text represents the data, tags indicate what the data is. In this example, the XML is storing student names as well as test scores associated with each student. Plain text is the actual data being stored. The plain text is shown in black and the tags are shown in green. As you can see, this file consists of plain text and tags.
