Help: XML and Schema

[zeny]

Hi everybody! I´m getting the error "The value of the element is invalid - The value '' is invalid according to its datatype 'Integer' " (I´m using Visual Studio 2005). How can a xsd element be either empty (like the empty string "") or an integer ???

Would be most thankfull for any help!

Best regards

2 possible ways I can think of.

1. use nil
a. Change schema to have attribute nillable="true"
b. In source, add xsi:nil="true" to the empty element.

2. base this value on an xs:string, and use a pattern.

<xs:simpleType>
	<xs:restriction base="xs:string">
		<xs:pattern value="[0-9]*"/>
	</xs:restriction>
</xs:simpleType>

The second case obviously works, but the first one, although it´s perfectly logical, doesnt work! Can anyone tell why???

You might have to define the xmlns:xsi namespace in the source as well.

Make the type a union between an empty string and xs:integer.
