Hi, I'm trying to figure out how to validate an element in XML with XML Schema that can either have no content or a couple of child elements. Example: <foo id="123"> <bar str="abc"/> </foo> <foo id="321"/> I can get XSD to validate one or the other but not accept both. Any ideas? (I have the minOccurs="0" on the <bar> element definition.) Cheers, aled.

This is an example schema: <xs:element name="foo" maxOccurs="unbounded"> <xs:complexType> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="bar"> <xs:complexType> <xs:attribute name="str" type="xs:string"/> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="id" type="xs:int"/> </xs:complexType> </xs:element> -- Martin Honnen --- MVP XML http://JavaScript.FAQTs.com/
