Moving to XML

More about Schemas [ii]: examples

• An attribute representing someone's age

  • <xsd:element name="age">
      <xsd:simpleType base="xsd:positive-integer">
        <xsd:maxExclusive value="150">
      </xsd:simpleType>
    </xsd:element>
    

• An attribute representing a UK bank sorting code (e.g. 68-59-13)

  • <xsd:simpleType name="sortcode" base="xsd:string">
      <xsd:pattern value="\d{2}-\d{2}-\d{2}">
    </xsd:simpleType>
    

• An attribute representing a UK grid reference (e.g. NX7951)

  • <xsd:simpleType name="gridref" base="xsd:string">
      <xsd:pattern value="[A-Z]{2}[0-9]{4}">
    </xsd:simpleType>
    

The pattern specification seems to have changed at some stage in the drafting process. The examples given in Learning XML don't work with Daniel Potter's tutorial applet. Treat all tutorials with care and refer back to the formal specification!
