Visual - XHTML Editor

Two Editing Modes

XHTML stands for W3C Extensible Hyper Text Markup Language. XHTML is aimed to replace HTML. While almost identical to HTML 4.01, XHTML is a stricter and cleaner version of HTML. XHTML is HTML defined as an XML application.

oXygen XML Editor offers two modes for editing the XHTML files. One is the Author mode that allows a visual editing, the other being the XML source editor.


You can edit the XHTML files using the text/source editing mode of oXygen XML Editor. The "as-you-type" validation and the powerful Content Completion Assistant are always on your side.

XHTML Source Editor

HTML Tables

You can create HTML tables, join or split cells, add or remove rows easily. oXygen will create all the column specifications for you.

Adjusting Column Widths


oXygen includes XHTML catalog and document templates so that you can start creating XHTML documents right away. Also a ready-to-use sample is provided in the samples project giving you a head start when working with XHTML. oXygen allows a very flexible document creation management through document templates. You can easily create new XHTML document templates from the editor content and you can publish your templates to share them with other users.

Remote Editing

oXygen XML Editor has built-in support for editing documents that are stored on remote servers through the protocols: FTP, SFTP and WebDAV, making it ideal for editing XHTML/HTML pages from your web server.

Import HTML Documents as XHTML

HTML documents can be converted to XML, allowing you to benefit from the XML support (XPath queries and XSLT transformations, for instance). During this process you can also associate an XHTML DTD with the newly converted document (either the strict or the transitional XHTML DTD) so the converted document is ready to be validated against the specified DTD.


Copy-and-Paste from Office/Web applications

Styled content can be inserted by copying content from Office applications (Microsoft Word and Microsoft Excel, Writer and Calc) and Web browsers (Mozilla Firefox, Microsoft Internet Explorer) and pasting it in the XHTML editor. The styles and general layout of the copied content (sections with headings, tables, list items, bold and italic text, hyperlinks, etc.) are preserved as equivalent XHTML XML elements by the paste operation.

Discontinuous selection

You can select multiple text ranges (discontinuous selection) or multiple elements in the Author mode and cut/copy/paste them.

Change Tracking

Change Tracking

Change Tracking is a way to keep a history of the changes made to a document. When change tracking is enabled, the inserted and deleted content is highlighted in the document allowing you to easily identify the affected regions. Tracked changes can be rendered in callouts (balloons) displayed at the side of the document, with connecting lines pointing to the changed content.

Change Tracking Toolbar

oXygen has some advanced change tracking features: it keeps record of the changes made to attribute values and element breaks (splits) and also renders changes from re-used content, such as DITA content reference, XIncluded modules, or external entities.

Multiple Authors Support

oXygen supports changes from multiple authors, rendering each author changes with different colors.

For each change oXygen stores the author and the date when that change was performed. The name of the author who is currently making changes and the colors can be customized from the Track Changes preferences page. It is possible to add comments to the changes.

Change Tracking in the Author page

In the screenshot you can see how various insert/delete changes made by various authors are displayed (the option to display changes as balloons is on).

Change Management

You can review the changes made by you or other authors and then accept or reject them using the Track Changes toolbar buttons or by using the Change Management dialog.

Review Comments

Callouts Support

When you annotate your XML documents, the comments are displayed in the Author mode as side callouts (balloons) showing additional information, such as the author and the comment time.

The comment support is not limited to a document type (DocBook or DITA, for instance). You can use it on any document that is opened in the Author editing mode. The comment data is stored in the XML document as processing instructions, so it will not interfere with your XML tool chain.

Comments in the Author page

You can access the comments actions from the application toolbar:Comments Toolbar

" oXygen XML Editor is the premier text editor for XML geeks, and an indispensable tool for O'Reilly's Production group. My team uses oXygen XML Editor for everything from simple XML editing to Schema validation and XSLT transformations. The digital production staff especially loves oXygen's built-in EPUB support, which eliminates a great deal of the grunt work that is usually entailed in editing EPUB files. The more we use oXygen, the more realize what a powerful tool it can be in digital and XML-based workflows."
