Element must have no character or element information item [children], because

自定义XSD对XML校验，eclipse校验出现如下错误：

XML内容：

<PrimaryKey>123456</PrimaryKey>

 

错误提示：

 

Element  must have no character or element information item [children], because the type's content type is empty

 

修改前的XSD定义：

 

<xs:element name="PrimaryKey" type="KeyType" nillable="false" maxOccurs="15"/>

  <xs:complexType name="KeyType">
    <xs:attribute name="type" default="STRING"  use="optional">
      <xs:simpleType>
        <xs:restriction base="xs:string">
          <xs:pattern value="\d+" />
        </xs:restriction>
      </xs:simpleType>
    </xs:attribute>
 </xs:complexType>

 

 

将 KeyType修改为继承自xs:string后通过。

<xs:complexType name="KeyType">
    <xs:simpleContent>
       <xs:extension base="xs:string">
          <xs:attribute name="type" default="STRING"  use="optional">
             <xs:simpleType>
		 <xs:restriction base="xs:string">
		      <xs:pattern value="\d+" />
		 </xs:restriction>
	     </xs:simpleType>
          </xs:attribute>
       </xs:extension>
     </xs:simpleContent>
   </xs:complexType>
