所以我正在尝试使用架构验证XML，但不断收到错误：
"S4s-elt-invalid-content.1：'ingredients_type'的内容无效。元素'元素'无效、放错位置或出现得太频繁。
这是我的 XML：

您的 XML 和 XSD 都有很多问题，以至于我停止跟踪，但这里有一些问题：
-
xs:element不能以xs:complexType的孩子出现。 一种更正是将xs:elements添加到xs:sequence。 -
这是
xsi:noNamespaceSchemaLocation，而不是xsi:noNameSpaceLocation。 -
当组件是 XML 中的属性时，不要将组件声明为元素。
-
注意拼写、拼写错误和大小写问题。
请注意，当必须修复 XML 和 XSD 时，对于最初的意图存在歧义。 下面的 XSD 现在成功验证了以下 XML，但请务必检查已修复的内容，以确保它符合您的意图。
