I have a XML file that is not valid respect to XSD but I can not understand what is the issue! It seems that XML is correct but It is not valid

Cvc-complex-type.2.4.a: Invalid Content Was Found Starting With Element 'decodifica_impianto'. One Of '{decodifica_impianto}' Is Expected., Line '3', Column '24'.

This is my XSD structue:

  </decodifica_impianto>
</tr_cdgn>

Can anyone help me to understand where is the issue? Regards Sin

  • Your XSD itself is not valid. It references components from unavailable namespaces. If you'd like further help, create an ***complete*** [mcve] that illustrates your problem. – kjhughes Jul 10 '20 at 14:16
  • Also, the namespace of your XML document is not the same as the target namespace of your XSD. – kjhughes Jul 10 '20 at 14:21
  • Maybe the XSD is not valid, because I ought to cut some parts for pasting in the site. But what is the issue of namespace? – sinaei Jul 10 '20 at 14:44
  • I also remove the name space here... So they have the same namespace in the original file.... – sinaei Jul 10 '20 at 14:48
  • The error saying that "decodifica_impianto" is expected but I have it in my XML file – sinaei Jul 10 '20 at 14:48
  • Not going to engage in ongoing back-and-forth in comments. [edit] your question and add a ***complete*** [mcve] as requested (and required) if you'd like help. – kjhughes Jul 10 '20 at 15:59

I found the root cause, we need to add elementFormDefault="qualified" tag in XS:schema
