XSD Miscellaneous Data Types
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:
| <prize disabled="true">999</prize> |
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="http://www.w3schools.com/images/smiley.gif" /> |
Note: If a URI has spaces, replace them with %20.
