The editing area in <oXygen/> consists of two tabs: the text based editing tab and the XML grid editor. The latter is available when editing files recognized as XML. By default, <oXygen/> opens the files in the text based editor.
The tabs are synchronized with each other, so you can quickly switch between them when required.
Most of the actions available in the text mode editor are available for the grid and have Undo/Redo support. You can easily identify nodes in the document using the find and replace action along with the XPath toolbar and the XPath builder.
The XML document is displayed in the XML Grid Editor as a structured layout of nested tables in which the text content can be modified without directly interacting the XML tags. <oXygen/> considers the child elements and attributes of the recurring elements as columns. The tables can be expanded and collapsed with a mouse click to show or hide the elements as needed. Also the document structure can be changed easily with drag and drop operations on the grid components.

There are two layouts available in the grid editor: the grid layout (tries to find and group the recurring elements in tables) and the tree layout (shows directly the structure of the XML document).

By grouping the recurring structures, <oXygen/> offers the possibility to manipulate the data with table specific operations:
Other operations, available on any node, include node insertion and deletion.
The grid behaves as a form, so you can use the well known keyboard navigation: arrow keys, page up/down, etc..
If the edited document uses an XML Schema (or a DTD, Relax NG Schema, etc..) you can use content completion. In the image below the grid editor is used to modify an XML Schema.

When inserting an element whose definition indicates a required content ( either attributes, sub-elements or both) <oXygen/> automatically adds those nodes in the grid.
The Find All Elements action is available in all the XML editor modes: Text, Author and Grid. It represents an easy way to search for XML elements by their tag names, attribute names and values.

The XML Grid Editor fully supports Unicode. It is possible to change the text orientation when you are editing XML documents containing right to left or bidirectional text.
You can customize the grid's appearance according to your needs. For instance you can change the font, the cell background, foreground, or even the colors from the table header gradients. The default width of the columns can also be changed.
In the following image the grid has been configured to use a high contrast color schema:
