XSD Miscellaneous Data Types

❮ Previous Next ❯

Other miscellaneous data types are boolean, base64Binary, hexBinary, float, double, anyURI, QName, and NOTATION.

Boolean Data Type

The boolean data type is used to specify a true or false value.

The following is an example of a boolean declaration in a schema:

<xs:attribute name="disabled" type="xs:boolean"/>

An element in your document might look like this:

<price disabled="true">999</price>

Note: Legal values for boolean are true, false, 1 (which indicates true), and 0 (which indicates false).

Binary Data Types

Binary data types are used to express binary-formatted data.

We have two binary data types:

  • base64Binary (Base64-encoded binary data)
  • hexBinary (hexadecimal-encoded binary data)

The following is an example of a hexBinary declaration in a schema:

<xs:element name="blobsrc" type="xs:hexBinary"/>

AnyURI Data Type

The anyURI data type is used to specify a URI.

The following is an example of an anyURI declaration in a schema:

<xs:attribute name="src" type="xs:anyURI"/>

An element in your document might look like this:

<pic src="https://www.w3schools.com/images/smiley.gif" />

Note: If a URI has spaces, replace them with %20.

Restrictions that can be used with the other data types:

  • enumeration (a Boolean data type cannot use this constraint)
  • length (a Boolean data type cannot use this constraint)
  • maxLength (a Boolean data type cannot use this constraint)
  • minLength (a Boolean data type cannot use this constraint)
  • pattern
  • whiteSpace
