help with matching invalid dates

[dizziedazz]

Can someone help me to create a pattern that identifies "Invalid" dates. Eg. 7/412/02 or 10/1902. Correct dates will be in mm/dd/yy(yy)? format.

Thanks

Hi,

Since you are using XML Schema you should check the date built in type and see if you can use that:
http://www.w3.org/TR/xmlschema-2/#date

Otherwise you can constrain the string type for instance like below (or you can invent more strict constraints):

Code: Select all

<xs:simpleType>

    <xs:restriction base="xs:string">

        <xs:pattern value="\d\d/\d\d/\d\d(\d\d)?"/>

    </xs:restriction>

</xs:simpleType>

Best Regards,
