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.
Who Uses Vex?
Vex provides several commands to edit a XML document.
This command opens a popup dialog which shows a list of elements that could be added to the document at the current cursor position. If you select one of the list items, the popup dialog is closed and the selected element is inserted.
The path of the current cursor position within the document structure is shown in the status bar. This can be an orientation if you want to add an element at a position that is not rendered explicitly (e.g. a new chapter between two existing chapters in Docbook).
This command duplicates the currently selected elements and inserts them at the beginning of the current selection. If there is nothing selected, 'Duplicate Selection' duplicates the element that surrounds the current cursor position.
The document's root element can, of course, not be duplicated.
