Open XML Files

XML (standing for Extensible Markup Language) is a set of rules meant to be used when encoding documents in machine-readable manner. XML files use tags for defining objects and their attributes.

An XML file esembles HTML ones in terms of formatting, but it also features different tags for representing objects and the information within each item.

The XML file format is largely used for storing and transferring data over the Internet or between apps, and it is supported by numerous applications.
