XML 具有嵌入式 HTML 和验证的架构

Question

我有一些 XML 这样的：

<Question id="question1" type="text" required="true">
  <Ask><b>Enter</b>some required text (required)</Ask>
</Question>

<Question id="question2" type="text" required="false">
  <Ask>Enter some text (optional)</Ask>
</Question>

我想允许在 <Ask> 标签内嵌入 html。

所以我在 XSD

中尝试了这个

 <xs:element maxOccurs="unbounded" name="Question">
     <xs:complexType>
        <xs:sequence>
           <xs:element name="Ask">
               <xs:complexType mixed="true">
                   <xs:sequence>
                       <xs:any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
           </xs:sequence>               
      </xs:complexType>
 </xs:element>

然而，当 reader 解析它时，它会抛出这个错误：

System.Xml.Schema.XmlSchemaValidationException: The element 'Ask' has invalid child element 'b'. List of possible elements expected: any element in namespace 'http://www.w3.org/2001/XMLSchema'.

我找到了这个 link，但它似乎不起作用？

XML Schema that allows embedding html

Answer 1

试试这个：

<xs:complexType mixed="true">
  <xs:choice minOccurs="0" maxOccurs="unbounded">
    <xs:any processContents="lax" />
  </xs:choice>
</xs:complexType>

或者看起来你必须使用 CDATA

<Question id="question1" type="text" required="true">
  <Ask><![CDATA[<b>Enter</b>some required text (required)]]></Ask>
</Question>
