XSD has a few other important data types, such as Boolean, binary, and anyURI.
<xs:boolean> data type
The <xs:boolean> data type is used to represent true, false, 1 (for true) or 0 (for false) value.
<xs:boolean> Example
Element declaration in XSD −
<xs:element name = "pass" type = "xs:boolean"/>
Element usage in XML −
<pass>false</pass>
Binary data types
The Binary data types are used to represent binary values. Two binary types are common in use.
- base64Binary − represents base64 encoded binary data
- hexBinary − represents hexadecimal encoded binary data
<xs:hexbinary> Example
Element declaration in XSD −
<xs:element name = "blob" type = "xs:hexBinary"/>
Element usage in XML −
<blob>9FEEF</blob>
<xs:anyURI> data type
The <xs:anyURI> data type is used to represent URI.
<xs:anyURI> Example
Element declaration in XSD −
<xs:attribute name = "resource" type = "xs:anyURI"/>
Element usage in XML −
<image resource = "https://www.adglob.in/images/smiley.jpg" />
