Why isn't my XML validating with the schema?
Question
So I am trying to validate the XML with the schema but I keep getting the error:
"S4s-elt-invalid-content.1: The Content Of 'ingredients_type' Is Invalid. Element 'element' Is Invalid, Misplaced, Or Occurs Too Often."
This is my XML:

Both your XML and XSD have so many problems that I stopped keeping track, but here are some of the issues:
xs:elementcannot appear as a child ofxs:complexType. One correction is to add thexs:elements toxs:sequence.It's
xsi:noNamespaceSchemaLocation, notxsi:noNameSpaceLocation.Don't declare components as elements when they're attributes in the XML.
Watch out for spelling, typos, and case issues.
Be aware that when both the XML and the XSD have to be fixed, there's ambiguity as to what was intended in the first place. The below XSD now successfully validates the below XML, but be sure to check what's been fixed to be sure it agrees with your intent.
