oXygen XML Editor 11.0

oXygen XML Editor 11.0 is developed as a Java-based XML editor supporting XML, XSL, TXT, XSD and DTD documents with the support of Unicode and the interface messages  translated in English, French, German, Italian and Romanian. It offers end tag auto-completion and a powerful code insight that guide the user to write valid XML content. The code insight can follow a DTD or an XML Schema or even can learn the structure from a partial edited document, allowing the rest the document to be created faster.
An important thing is manipulating XML content and XSLT is the normal way to do this. XML and XSL documents can be easily associated one with the other and the transformation results can be viewed as text or XHTML.
An XPath console is present to assist the user in testing the results of XPath expressions.
Oxygen validates XML, XSL, XML Schema and DTD content, reporting errors with description and line number information. More documents can be logically organized in projects. The syntax highlight can be customized. If the indentation is not right then the pretty print facility will solve this. Oxygen can run over the web through Java Web Start.
It comes with Docbook DTD and stylesheets. Includes the Apache FO Processor, being able to generate PDF and PostScript. Other FO processors can be configured as plugins.

Major Features:

1. WYSIWYG XML Editor (Visual XML editor): The Author mode of the XML Editor demonstrates a new productive way of editing XML documents, similar to a word processor.
2. Intelligent XML Editing: The context sensitive content assistant is changing the way you edit documents, helping you create valid content all the time.
3. Extensible XML Editor: Starting with version 9 adds a new concept called Document Type that solves the problem of providing ready to use support for a framework or an XML language. The Document Type concept is used to provide the built in support has for a number of XML frameworks (DITA, DocBook, TEI) but, more importantly, it can be employed to provide support for a user defined framework that needs to be shared with other users.
4. XML Grid Editor: The 's grid editor allows you to edit repetitive XML content in a special layout similar to a spreadsheet application, without the need to interact with markup.
5. XML Outliner: XML Editor comes along with a powerful outliner which is automatically synchronized with the document changes.
6. XInclude Support: XML Editor supports XInclude which is a standard for building up XML documents from smaller pieces, being a replacement for the external entities.
7. XML Validation and Well-Formedness Check: The XML validation can be done by checking the documents against a schema. XML Editor supports: XML Schema, DTD, Schematron and Relax NG schemas.
8. XML Formating and Indentation.: An useful utility is the XML document formatter.
9. Unicode and Internationalization: XML Editor supports a large number of text encodings. Unicode is fully supported.
10. XML Diff and Merge Tool: A complete diff and merge solution is available in XML Editor. It offers both directory and file comparison, six different diff algorithms and multiple levels of comparison.
11. XPath support: XPath is a language for addressing specific parts of an XML document. XPath, like the Document Object Model (DOM), models an XML document as a tree of nodes. An XPath expression is a mechanism for navigating through and selecting nodes from the XML document. You can executes XPath queries on opened documents. Both XPath versions 1.0 and 2.0 are supported.
12. XML Digital Signature and XML Canonicalization: The digital signature is a requirement when exchanging information in an untrusted network. Since XML is used for content storage it is important to be able to sign the XML files or messages.
13. Tree Editor: XML documents can be viewed/edited in a graphical tree. The tree editor is handy for large size documents.
14. Helper Views: There is a set of panels located at the side of the editing area helping the XML editing. They present the model of the edited XML element, the available attributes and entities.
