WebSphere Application Server - IBM Redbooks

When you create an XML file from a DTD or XML schema file, you will have to
select a root element. With an XML schema, you also select a namespace.
XML schema wizard
Studio Site Developer provides the Create XML Schema wizard to take you
through the process of creating a new XSD file. To create a new XML schema
file, you have the following options:
► To generate it from scratch, select File -> New -> Other -> XML -> XML
Schema (or use the icon).
► To generate it from an existing DTD or XML file:
– From the context menu of a DTD (.dtd) file or an XML (.xml) file in the
Navigator, select Generate -> XML Schema.
– From within a DTD file open in the editor, select DTD -> Generate XML
Schema.
From within an XML file open in the editor, select XML -> Generate XML
Schema.
DTD wizard
A Document Type Definition (DTD) has two purposes:
► To serve as a framework and provide a set of elements and attributes that will
be used in the XML “templates” used by the application to generate XML
documents from raw data retrieved from the back end.
► To validate incoming XML documents sent by the supplier in reply to outgoing
purchase orders generated by the customer application.
