XSD - Multiple type content validation

Question

i want to validate an xml file of the Structure:

<element>255</element> <!-- Integers are allowed from 0 to 255 -->
<element>Impossible</element> <!-- "Impossible" should be the only valid string -->

is this even possible with xsd? (Without using the string-pattern-matching for the integers)

Best regards

Answer 1

You need a union of integer and restricting string types. Look at this article for example.
