Can I check whether a particular element has some pattern only if it is not null

[prathibha, ar]

Hi,
I have an xml file and i am validating this xml file by means of xsd.
I have an attribute called date which can be null also. but if suppose it is not null then i want to check for the pattern for it.
Is it is possible.
Thanks and regards

You can do that as follows
<xsd:element name="Date" nullable="true" type="xsd:date">

Thankyou for the reply.
I tried the think which u had told . but it is giving the error
as
Attribute 'nullable' cannot appear in 'element'.
What may be the reason for this.

Hi there,
I think you need something like:
<xsd:element name="Date" type="xsd:date" nillable = "true" />
Hope it works.
