Question

I don’t understand why the xsd rule I have created for a date is not working.
The rule is: <xs:element name="scan_date" type="xs:date" />
which, accoring to XML Schema Date on W3Schools is specified in the following form “YYYY-MM-DD”, yet when the XML Parser in SQL encounters <scan_date>2006-12-15</scan_date> it fails because it doesn’t accept the date as valid, yet if I swap the 12 and 15 round it does.

Answer 1

A possible solution using xs:string and a regex restriction:

<xs:element name="scan_date" type="dateType"/>

<xs:simpleType name="dateType">
    <xs:restriction base="xs:string">
        <xs:pattern value="\d{4}(0[1-9]|1[012])(0[1-9]|[12][0-9]|3[01])"/>
    </xs:restriction>
</xs:simpleType>
