Vex User Guide


What is Vex?

Vex is a Visual Editor for XML that hides the raw XML tags from the user, providing instead a word processor like interface. Vex uses standard DTD files to define document types and CSS stylesheets to define document layout. Vex contains definitions for DocBook and DITA. To edit other XML formats only a DTD and a CSS are needed.
