XML (file format)

XML or eXstensible Markup Language is a file format that uses a nested structure where the "tags" like <Cat> contain other tags inside them, like <firstName>. This format is good for organizing the layout of a document in a tree-like format, just like HTML, where we want to nest elements like a sentence within a paragraph, for example. XML does not carry any information about how to be displayed and can be used in a variety of presentation scenarios.
