Altova XMLSpy 2020 Enterprise Edition

An XML Schema describes the structure of an XML document. An XML document can be validated against an XML Schema to check whether it conforms to the requirements specified in the schema. If it does, it is said to be valid; otherwise it is invalid. XML Schemas enable document designers to specify the allowed structure and content of an XML document and to check whether an XML document is valid.

 

The structure and syntax of an XML Schema document is complex, and being an XML document itself, an XML Schema must be valid according to the rules of the XML Schema specification. In XMLSpy, Schema View enables you to easily build valid XML Schemas by using graphical drag-and-drop techniques. The XML Schema document you construct is also editable in Text View and Grid View, but is much easier to create and modify in Schema View.

 

Objective

In this section of the tutorial, you will learn how to edit XML Schemas in Schema View. Specifically, you will learn how to do the following:

Create a new schema file

Define namespaces for the schema

Define a basic content model

Add elements to the content model using context menus and drag-and-drop

Configure the Content Model View

 

After you have completed creating the basic schema, you can go to the next section of the tutorial, which teaches you how to work with the more advanced features of XML Schema in XMLSpy. This advanced section is followed by a section about schema navigation and documentation in XMLSpy.

 

Commands used in this section

In this section of the tutorial, you will use Schema View exclusively. The following commands are used:

 

ic_component

Display Diagram (or Display Content Model View). This icon is located to the left of all global components in Schema Overview. Clicking the icon causes the content model of the associated global component to be displayed.
