XML Schema (XSD) Editor
The oXygen XML Schema editor offers
powerful content completion support, a quick assist tool that is always ready to provide
hints, a Components Presenter view, and multiple refactoring actions.
W3C XML Schema documents can be edited and validated with oXygen. The Quick
Assist feature improves the development work flow by offering quick access to the most
commonly used actions during development of XML Schemas.
Easy Identification of XML Schema Component References
All the occurrences of an XML Schema component are highlighted
in the text when you place the cursor near the component name.
The occurrences bar from the right side of the editor displays a summary of the
component references in the XML Schema file.
The component declaration is rendered with a darker color to make it easier to
Content Completion Assistant Offers the List of Components from Included/Imported
XML Schema editing is simple with oXygen, since you can
insert references to components from other XML Schema files and you are assisted by
the Content Completion Assistant. oXygen automatically detects the modified
included/imported schemas and adjusts the list of proposals in the Content Completion
Rename Component Schema Refactoring Action
This action allows you to rename any schema component (element,
type, group, named pattern, etc.) The scope can be set to the current file, all the
files in project, or the set of files determined by include/import instructions
starting with a specified file.
The rename refactoring support is available for both XML Schema and Relax NG
A preview option allows you to review and approve the changes that will be made on
multiple schemas. The changes are presented in a side-by-side synchronized view that
compares the initial version with the result after applying the refactoring
Find References and Declarations of XML Schema Components
You can find declarations or references of XML Schema
components. The search scope can be the current file, the current project, or a group
Content Completion Assistant Shows the Schema Documentation
When you are editing an XML schema, oXygen helps you with a schema-driven
Content Completion Assistant that also displays documentation for the element and
Custom Schema for XML Schema Annotations
XML Schemas contain annotations for providing additional
information, such as documentation or application-specific information. For instance,
a schema might contain documentation for its components in XHTML or Schematron
embedded rules. You can specify a schema for these annotations and oXygen will use
that for providing content completion proposals.
Schema Model View
The Model view provides schema-related information for the document elements and
attributes. The content model, element type, attributes, attribute type, and
constraints are presented in a compact manner, giving you the insight of the document
schema while editing or browsing the document.
Link to Specification for XML Schema Errors
oXygen is the first XML editor that links the
error directly to the part of the specification that explains it. The error messages
contains an information field that will open the browser on the "XML Schema Part
1:Structures" specification at exactly the point where the error is described. This
allows you to better understand the error message.
Flatten an XML Schema
Sometimes it is useful to aggregate the set of files that
compose an XML Schema into a single file. The Flatten Schema refactoring action allows
you to do this. The action also handles xs:redefine elements by
assigning a unique name to each redefined type or group.
Visual Schema Text Editor
oXygen offers a side-by-side presentation of the schema
source and diagram. The diagram is synchronized in real time with the source editor.
Selecting an element in the diagram highlights the corresponding element in the source
editor, while moving the cursor in the source editor changes the selection in the
The schema diagram renders all the XML Schema components and
allows you to quickly navigate to the referenced definitions (elements, attributes,
types, groups, etc.)
Two types of visual diagrams are available for a schema:
- Full Model View
The Full Model view provides a one-to-one correspondence
between the schema components and the graphical nodes. References to the
components can be expanded in-place within the diagram (element or attribute
references, or base types). Editing actions are available on the Full Model view,
allowing the addition of new child or sibling elements on the fly so that the
schema remains valid.
- Logical Model View
The Logical Model view displays a more compact diagram
obtained by resolving the references, type extensions and restrictions, or
A list with the defined schema components (elements, attributes, simple and
complex types, groups, and attribute groups) presented in the Outline view simplifies
the navigation through large schemas.
The smooth editing and the clear and suggestive rendering make schema editing
easier than ever.
The Visual Schema Editor is integrated in the oXygen
standalone distribution and the Eclipse IDE plugin. It is activated when opening an
XSD (XML Schema) file.
The diagrams can be made smaller or larger, depending on the zoom settings of the
font size. These settings are taken into account when the diagram is printed.
Converting Between Grammar Languages
The Generate/Convert Schema tool allows you to convert a DTD or
Relax NG (full or compact syntax) grammar, or a set of XML files, to an equivalent XML
Schema, DTD, or Relax NG (full or compact syntax) grammar. Where exact equivalence is
not possible due to limitations of the target language, oXygen generates an
approximation of the source grammar.
Advanced options allow the user to customize various conversion parameters.
XML Schema Regular Expressions Builder
The Regular Expressions Builder helps you construct and test
regular expressions that are allowed in XML Schema restriction patterns.
oXygen provides a set of regular expression patterns
organized in categories, and a test area for checking the instances accepted by the
expression. The Content Completion Assistant provides an additional level of support
when editing in the regular expressions editor.
