Question

我在尝试使用我的XSD文件验证我的xml文件时收到错误The Content Of 'all' Must Match (annotation?, Element*). A Problem Was Found Starting At: Sequence.。我使用了<xs:all>，因为size的数量可能会在子根节点中发生变化。我不确定是否应在<xs:all>代码之后或之前添加属性标记。

这是我的xml文件

<?xml version="1.0" encoding="UTF-8"?>
<catalog>
   <product description="Cardigan Sweater" product_image="cardigan.jpg">
      <catalog_item gender="Men's">
         <item_number>QWZ5671</item_number>

         </size>
         <size description="Large">
            <color_swatch image="red_cardigan.jpg">Red</color_swatch>

            <color_swatch image="black_cardigan.jpg">Black</color_swatch>
         </size>
         <size description="Large">
            <color_swatch image="navy_cardigan.jpg">Navy</color_swatch>
            <color_swatch image="black_cardigan.jpg">Black</color_swatch>

         <size description="Extra Large">
            <color_swatch image="burgundy_cardigan.jpg">Burgundy</color_swatch>
            <color_swatch image="black_cardigan.jpg">Black</color_swatch>
         </size>
      </catalog_item>
   </product>
</catalog>

这是我的XSD文件。不知道我的a是否已被放置在正确的位置。

假设您要在<size>中允许多个<catalog_item>元素，则需要在maxOccurs="unbounded"元素上设置size。

<xs:element name="size" maxOccurs="unbounded">

之后，您需要更正<size>的内容定义 - 此处使用<xs:all>没有意义（请记住<xs:all>表示＆＃34;} 这些元素在此上下文中只需要发生一次，无论顺序如何＆＃34;）。这应该符合您的要求：

    <xs:element name="size" maxOccurs="unbounded">
        <xs:complexType>
            <xs:sequence>
              <xs:element name="color_swatch" maxOccurs="unbounded">
                <xs:complexType mixed="true">
                  <xs:attribute name="image" type="xs:string"/>
                </xs:complexType>
              </xs:element>
            </xs:sequence>
            <xs:attribute name="description" type="xs:string"/>
        </xs:complexType>
    </xs:element>

PS：你忘记了＆＃34; xs:＆＃34;最后两个属性声明的前缀：

 <attribute name="description" type="xs:string"/>
 <attribute name="product_image" type="xs:string"/>

错误：“所有”的内容必须匹配
