Oxygen XML Author is a cross platform Visual XML Editor. Supports visual XML editing driven by CSS stylesheets with specializations for DITA, DocBook 4 and 5, TEI P4 and P5, XHTML. This support includes document templates for easily creating new XML instances, CSS for WYSIWYG like editing, interface actions for creating and editing lists, tables and marking up specific content, XML Catalogs for faster access to resources, schema files for validation, transformation scenarios to convert from XML to HTML and/or PDF.
The DITA Maps Manager allows viewing and editing of DITA map files. It acts also similar with a project manager allowing you to easily open different topics/concepts for editing. The toolbar, the contextual menu and drag and drop actions allow you to easily edit the map content. The XML content included using XInclude or XML entities is presented in place as a read only block that can be collapsed/expanded.
With the navigation links support it becomes easy to go from a DITA conref to the referred content, from a DocBook link to the target element or from an XInclude reference to the included content, etc. by just a single click. Hiding the XML markup can have the disadvantage of losing the visual markers (the element tags) between text nodes.
Fortunately, Oxygen has a solution for this: the location tooltip combined with the marks from the XML outliner and with the location bar allows you to know at each moment what is the current location in the document.
Additionally, there are several levels of display for XML element tags ranging from no tags to full tags. The WYSIWYG like editor was closely integrated in Oxygen as an editor tab called Author next to the Text and Grid editing modes. All the Oxygen powerful editing actions are also available in the Author mode.
These include: spell checking, validation, search and replace, XPath execution, etc. Also all side views that Oxygen provides are offering information when editing in Author mode.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
