Using XSD i want to only accept date of the format YYYYMMDD in my xml field .. So how can i do that

I saw this in an example will this work ??

XML schema defines dateTime as ISO8601 with some exceptions and you should stick with this, otherwise you will get serious interoperability issues. If you want to send/receive date using different format, use simpleType with regular expression restriction and parse/format the date in your application code:

<xs:simpleType name="CustomDate">
    <xs:restriction base="xs:string">
        <xs:pattern value="\d{8}"/>
    </xs:restriction>
</xs:simpleType>

If you really want to mess around with built-in types (highly inadvisable), your XML framework/library might have some support for that. For instance in Java/JAXB you can apply custom transformers/formatters to any type, so that in client/server code you are still using Date object (not the 8-digit String), but it is marshalled/unmarshalled using your custom routine.
