XSD How To?

A reference to a DTD or an XML Schema is possible for the XML documents.

A Simple XML Document:

Note.xml:

A DTD File:

Note.dtd:

Explanation:

We are using the above DTD file to define the elements of the XML document note.xml. The four child elements: “to, from, heading, body” of the note element is defined in the first line. The type of the child elements: to, from, heading, body elements are defined as “#PCDATA”, in the line 2-5.

An XML Schema:

Note.xsd:

Explanation:

In the above example, we are using an XML Schema file to define the elements of the XML document “note.xml”. The note element contains other elements and is thus a complex type. The elements: to, from, heading, and body, do not contain other elements and are thus simple types.
