Using XS:date i want date in format YYYYMMDD

Question

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 ??

xs:date will be of the form YYYY-MM-DD. Why do you care what format the date is, in an xml? your app should take care of converting this to the required format. — asgs, Feb 18 '11 at 09:43

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.

Is this right ?? is label CustomDate mandatory – Praneel PIDIKITI Feb 18 '11 at 10:19
No, you can't use both `type` on element and nested `simpleType`. Use only: ... and live with strings. – Tomasz Nurkiewicz Feb 18 '11 at 11:04

I have a legitimate case where the date format is defined by healthcare standard as YYYY[MM[DD[hh[mm[ss]]]]]. Problem is XSLT does not support that format, and modifying the document xs:date is out the question. – code-gijoe Nov 28 '12 at 19:33
are you talking about hl7? How did you later parse it – JohnTheBeloved Sep 30 '17 at 00:21
