Create an XSD that validates all three XML files:

1.

4   2

8   6

4   2

2. Intentionally create an error by giving the schema an XML file with valid structure but invalid data. (For example, a with no child element.)

3. Take a screenshot showing the schema catching the error in 2.

Remember, you don’t know if your schema is working unless it gives you an error!

4. Verify that the schema gives you an error for an invalid file, but accepts all three valid files.
