The XML Editor is an interactive tool for viewing XML files and for creating new data or annotating text retrospectively in XML. The XML Editor has three main views - the Design View, the Source View and the WYSIWYM View (="What You See Is What You Mean").

In the Design View, the XML file is represented by a tree structure, which provides a clear overview of highly structured data.

The Source View enables you to view and work directly with the XML code. It includes many text editing features, such as the following:

• Syntax Highlighting: the various syntactic elements of an XML file are marked in different colors
  

• Content Assist: the XML Editor suggests possible elements or attributes based on an XML schema or the elements already present in the document 

• Unlimited undo and redo capability
  

• Display of the Content Model (possible elements) and documentation of current elements if present in the schema

In the WYSIWYM View the XML document can be edited in a format designed for print or for online editions. The display is generated by a CSS (in future versions, you will be able to chose and edit your own CSS). Labels that visualize the XML elements can also be displayed if desired.
