java - cvc-数据类型-valid.1.2.1 : 'mylns:xsi' is not a valid value for 'NCName'

Question

架构:

<xs:complexType>
  <xs:sequence>
    <xs:element ref="FileCreationList"/>
    <xs:element ref="DivestedExample"/>
  </xs:sequence>
  <xs:attribute name="mylns:xsi" type="xs:string"/>
  <xs:attribute name="xsi:schemaLocation" type="xs:string"/>
</xs:complexType>

错误:

Multiple annotations found at this line:
    - s4s-att-invalid-value: Invalid attribute value for 'name' in element 'attribute'. Recorded reason: cvc-datatype-valid.1.2.1: 'mylns:xsi' is not a valid 
     value for 'NCName'.
    - src-attribute.3.1: One of 'ref' or 'name' must be present in a local attribute declaration.
    - s4s-elt-invalid-content.1: The content of '#AnonType_File' is invalid. Element 'attribute' is invalid, misplaced, or occurs too often.

Answer 1

属性名称声明必须是 NCNames (非殖民地名称):

NCName ::= (Letter | '_') (NCNameChar)*  /* An XML Name, minus the ":" */

从 mylns:xsi 和 xsi:schemaLocation 中删除冒号以消除错误。

注意事项:

• 不要在元素的 XSD 声明中包含命名空间前缀或属性名称。

• 不要将 xsi:schemaLocation 声明为 XSD 中的属性；宣布并引用 http://www.w3.org/2001/XMLSchema-instance命名空间:

  <root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.example.com/name try.xsd"/>
