About XML in Microsoft Visio

Beginning in Microsoft Visio 2002, the Extensible Markup Language (XML) is supported as a native file format, making it possible to share your Visio drawings across multiple platforms.

Additionally, the Visio 2002 object model provides new properties and methods that make it possible for solution developers to store well-formed, solution-specific XML data within a Visio document.

For details about working with XML in Visio 2002, see the Microsoft Developer Network (MSDN) Web site.
