你好我一直在寻找这个问题大约一个小时，我什至找不到这意味着什么。

这是我的 XML shema 代码：

<xsd:element name="game">
    <xsd:complexType>
        <xsd:sequence>
        <xsd:element name="info" minOccurs="0" maxOccurs="1" type="infoType">

                    <xsd:element name="i" type="descriptionType" ></xsd:element>
                    <xsd:element name="b" type="descriptionType"></xsd:element>
                </xsd:choice>
            </xsd:complexType>

这是我得到的解析器错误。

game.xsd:25: 
  element complexType: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}element': 
  The attribute 'type' and the child are mutually exclusive. 
game.xsd:51: 
  element attribute: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}complexType': 
  The content is not valid. Expected is (annotation?, (simpleContent | complexContent | ((group | all | choice | sequence)?, ((attribute | attributeGroup)*, anyAttribute?)))). 
game.xsd:58: 
  element simpleType: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}attribute': 
  The attribute 'type' and the child are mutually exclusive.

  element simpleType: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}attribute':

这是一个大学项目，我必须在 6 小时内上交。我希望我能在这段时间内找到解决方案。

谢谢

属性“类型”和子级是互斥的。

在screenname( game.xsd:25) 的元素定义中，两者都将元素类型定义为xsd:string在属性中，并将其定义为complexType使用子元素。您可能正在寻找具有特定属性和字符串内容的类型？

<xsd:element name="screenname" minOccurs="0" maxOccurs="4">
  <xsd:complexType>
    <xsd:simpleContent>
      <xsd:extension base="xsd:string">
        <xsd:attribute name="player" use="required" type="xsd:string" />
      </xsd:extension>
    </xsd:simpleContent>
  </xsd:complexType>
</xsd:element>
