oXygen Tree Editor

The Tree editor is very helpful when you are working with large documents due to its small memory footprint.

For quick navigation in a document you can use the upper left panel, which displays the current path of the document. Each button from the panel gives you access to all the XML nodes at the same level.

The Model view shows detailed information about the attribute or element that you are working with. Element and attribute annotations are also presented here, if they are available in the XML Schema of the document.

The Entities view displays a list of defined entities that you can insert within your document. It allows you to insert the selected entity after the current node as the next sibling, first child of the current element, or last child of the current element.

The All Elements panel displays a list of the defined elements that you can insert into your document. It allows you to insert the selected element after the current node as the next sibling, first child of the current element, or last child of the current element.

" 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."
