I’m trying to validate my XML document against my XML schema.

This is my schema:

  </Puiss>
  <Total Unite="MWh">5961</Total> 
  </OME>
</MSG>

Now when I’m validating the document (via Eclipse) I get following message:

Not valid. Error – Line 18, 21: org.xml.sax.SAXParseException;
lineNumber: 18; columnNumber: 21; cvc-complex-type.2.4.a: Invalid
content was found starting with element ‘Puiss’. One of ‘{Puissance}’
is expected.

Error – Line 69, 9: org.xml.sax.SAXParseException; lineNumber: 69;
columnNumber: 9; cvc-complex-type.2.3: Element ‘OME’ cannot have
character [children], because the type’s content type is element-only.

Error – Line 70, 7: org.xml.sax.SAXParseException; lineNumber: 70;
columnNumber: 7; cvc-complex-type.2.3: Element ‘MSG’ cannot have
character [children], because the type’s content type is element-only.

This messages doesn’t make any sense, and it’s very hard (impossible?) to search the web for a solution.

The first error at least is very clear – according to your schema the next-to-last child element of OME should be named Puissance, but the parser has found Puiss instead. In particular, reading the rest of your schema it looks like it’s expecting

<Puissance>
  <Puiss Unite="MW">
    <!-- Val elements as before -->
  </Puiss>
</Puissance>

If this is your own schema you may want to replace the

<xs:element name="Puissance" type="PuissType" />

in your OMEType with a simple

<xs:element ref="Puiss" />

For the other two errors I agree, they don’t seem to make much sense unless there’s some invisible non-printing characters in the XML, but I’ve known Eclipse get quite confused by certain classes of error in the past and start reporting problems that aren’t there – once you fix the first error you may find the others disappear too.
