Why am I getting org.xml.sax.SAXParseException when validate XML against XSD?

Question

Trying to make proper XML, but keeping getting this error :

Error - Line 13, 16: org.xml.sax.SAXParseException; lineNumber: 13; columnNumber: 16; cvc-complex-type.2.4.a: Invalid content was found starting with element 'me:myself'. One of '{"urn:Test.Namespace":myself}' is expected.

Testing here :

Code: .xml:

Answer 1

You put "name", "surname", ... inside your "myself" element. This means that you use it as a ComplexType. However, your xsd file doesn't states that "myself" is a ComplexType. You must define your "myself" element in the xsd file to be of ComplexType, just as you did for your "laptopy" element for instance.

Also, don't use "me:myself" or "uek:copyright", etc. Just use "myself" and "copyright".

Finally, your "group" element should have the integer type (as your xsd states), but you use it with a string "Kr1013".

See the fixed XML code bellow which is now well formed and valid with regards to your XSD schema (which I did not modify):
