XML Editor

The content completion support based on XML Schema determines the type of an element, and all the types that are derived from it, and presents their qualified names (resolved in the current context) as possible values for the xsi:type attribute.

When setting this option (Preferences / Editor / Save / Check for errors) the editor will try to validate the modified documents before they are saved. If the document is invalid you are asked if you want to proceed saving it or if you want to cancel the save operation.

The check for IDREFS in Relax NG is now configurable. You can set the parser to take into account the IDs from the document or to ignore them.

XInclude can be used to compose large documents validated against RelaxNG schemas.

Oxygen adds an option for checking if documents can become valid according with a Relax NG schema by completing missing markup, that is if it can be transformed in a valid document only by adding elements and attributes without deleting anything.

You can define some mappings between proxies and namespaces that will be used by the XPath evaluator.

A Copy XPath contextual action was added to easily get the XPath expression that selects the current element. You can paste it in the XPath evaluator and edit it further.

An XPath filter has been added to the Find/Replace dialog box. This allows you to perform searches or replacements only in the nodes that are included in the XPath result. It is also possible to change the direction of the search.

For people who use modular DocBook the management of entity references can become very time consuming, especially when the number of XML files is high and even more so when they are managed in a folder structure. Oxygen provides a way of selecting the files that represent the external entities and generate a DTD subset declaring the entities.

You can convert a section of text to character entities, or convert a section composed of character entities back to text.

You can select an element and correct its indentation. This is useful when you do not want to alter the indentation of other elements in the document.

It is possible to select the text from the editor and then drag it to another location in the document. This is faster than using the cut and paste actions.

This is an quick way of navigating to the changes locations in the document and to the areas that were selected. Each time you modify the document or you select some region of it the editor keeps track of that position. The buttons for moving forward and backward through the history are located on the main toolbar.

Oxygen contains the latest version of the Basic Saxon XSLT and XQuery Processor from Saxonica Limited. and it has ready-to-use support for the Schema Aware version.

Oxygen includes the DocBook DTD version 4.4 and the DocBook XSL stylesheets version 1.68.1.

The Saxon.NET XSLT 2.0 processor can be used as an XSLT processor for XSLT transformations from within Oxygen.

FXSL - the Functional Programming Library for XSLT created by Dimitre Novatchev is included in the Oxygen 6.0 distribution under frameworks. This offers you a lot of XSLT stylesheets that are ready to be imported in user stylesheets, to give you access to a lot of additional functionality. One of the most impressive examples is spell checking implemented in XSLT.
