XML

XML (Extensible Markup Language) is way to repurpose data in a file or automate the process of replacing the data in one file with data from another file. XML employs tags to describe parts of a file—a heading or a story, for example. These tags mark data so it can be stored in an XML file and handled appropriately when it is exported to other files. Think of XML as a translation mechanism for data. XML tags label text and other content in a file so that applications can recognize and present the data.

In Adobe InDesign, for example, you can create a Heading1 tag and assign it to each first-level heading in a document. After you save the document as an XML file, the Heading1 content can be imported and put to use—by any application that can read XML—as a web page, printed catalog, directory, price list, or database table.
