Validation Error Examples on Complex Datatypes
This section describes a tutorial example on XML document validation errors related to a complex datatype defined a schema.
To see some examples of the validation errors on elements using complex datatypes, I wrote the following XML document, term_error.xml:
<?xml version="1.0"?> <term update="Yesterday" note="To be updated."> <source>Internet</source> <name>Extensible</name> <definition>Capable of being extended.</definition> </term>
Of course, this XML document does not conform to term.xsd. Here are the errors generated from XsdSchemaValidator.java:
herong> java XsdSchemaValidator term.xsd term_error.xml Error: Line number: 2 Column number: 48 Message: cvc-datatype-valid.1.2.1: 'Yesterday' is not a valid value for 'date'. Error: Line number: 2 Column number: 48 Message: cvc-attribute.3: The value 'Yesterday' of attribute 'update' on element 'term' is not valid with respect to its type, 'date'. Error: Line number: 2 Column number: 48 Message: cvc-complex-type.3.2.2: Attribute 'note' is not allowed to appear in element 'term'. Error: Line number: 3 Column number: 10 Message: cvc-complex-type.2.4.a: Invalid content was found starting with element 'source'. One of '{name}' is expected. Failed with errors: 4
