And the response I get is:我得到的回应是:
"Cannot find the declaration of element 'rootItem'.
Any ideas?有任何想法吗?
your xml instance uses the default namespace xmlns="http://www.w3schools.com"
which is not defined in your schema.您的 xml 实例使用您的架构中未定义的默认命名空间xmlns="http://www.w3schools.com"
。 I don't know which part of your data is changeable, but you either have to remove the namespace in the XML or add it as <xs:element name="rootItem" xmlns="http://www.w3schools.com">
in your schema.我不知道您的数据的哪一部分是可更改的,但是您必须删除 XML 中的命名空间或将其添加为<xs:element name="rootItem" xmlns="http://www.w3schools.com">
在您的架构中。
(Have a look at the comment of Michael Kay where the right action to correct the schema file is mentioned) (查看 Michael Kay 的评论,其中提到了纠正架构文件的正确操作)
将目标命名空间添加到架构:
<xs:schema targetNamespace="http://www.w3schools.com" xmlns:xs="http://www.w3.org/2001/XMLSchema">
