joecool2005 Posted June 2, 2006 Share Posted June 2, 2006 Hi,I have a tag in XML like this:<myemail email="john@hotmail.com" />and I define my regular expression to validate the email.But sometime the email attribute can be empty like this<myemail email="" />How can you define a regular expression for that situation?ThxJoe Link to comment Share on other sites More sharing options...
kgw Posted June 7, 2006 Share Posted June 7, 2006 Hi,I tried the following and it seems that using type=string allows you to have empty attribute. (but if you change to integer, email can't be empty) <xs:element name="myemail"> <xs:complexType> <xs:attribute name="email" type="xs:string" use="required"/> </xs:complexType></xs:element> Link to comment Share on other sites More sharing options...
