验证 XML 内容时出错:元素不能包含空格.内容模型为空 [英] Error validating the XML content: The element cannot contain white space. Content model is empty

问题描述

我在尝试验证 qti xml 文档时一直遇到此错误.这是xml文档:

Hi I keep having this error while I try to valide a qti xml document. Here is the xml document:

     <respcondition title="Correct" >
      <conditionvar>
       <not>
         <varequal respident="1">A</varequal>
       </not>
       <varequal respident="1">B</varequal>
       <not>
            <varequal respident="1">C</varequal>
       </not>
      <varequal respident="1">D</varequal>
      </conditionvar>
        <setvar action="Set">1</setvar>
       <displayfeedback linkrefid="Correct"/>
     </respcondition>

这是验证xml的xsd片段

Here is the fragment of xsd that valide the xml

请问有人可以帮忙吗?我已经尝试解决这个问题几天了..谢谢干杯

Please can anyone help? I've been trying to fix this for for a few days now.. Thanks Cheers

找到答案:

好的，我找到了答案.我改变了条件变量定义.现在它正在工作.谢谢大家的帮助

Ok I've found the answer. i've changed conditionvar definition. Now it's working. Thanks you all for your help

    <xs:element name="or" type="orThirdPartyType" />
    <xs:element name="other" type="otherThirdPartyType" />
  </xs:choice>
  <xs:element name="varequal" type="varequalThirdPartyType"   minOccurs="0" maxOccurs="unbounded" />

</xs:complexType>

感谢您的帮助.

推荐答案

根据您的架构，在您的 元素中， 或 或 是预期的.无论是哪种情况，它都可能发生零次或多次(minOccurs="0" maxOccurs="unbounded").但是， 元素必须恰好出现一次，因为没有为其设置 minOccurs 和 maxOccurs(默认值为 <每个代码>1).后面跟着零个或多个 元素.

According to your schema, in your <conditionvar> element, either <not> or <or> or <other> is expected. Whichever it is, it may occur zero or more times (minOccurs="0" maxOccurs="unbounded"). However, the <choice> element must be there exactly once, as minOccurs and maxOccurs aren't set for it (default value is 1 for each). This is followed by zero or more <varequal> elements.

由于我不确定您打算将什么视为有效，因此我无法提供明确的更正架构片段，但我认为您实际上想要设置 minOccurs="0" maxOccurs="unbounded"对于 conditionvarThirdPartyType 中的 元素，如下所示:

As I am not sure what you intend to consider valid, I cannot provide a definitive corrected schema fragment, but I think that you actually want to set minOccurs="0" maxOccurs="unbounded" for your <sequence> element in conditionvarThirdPartyType, as in so:

<xs:complexType name="conditionvarThirdPartyType">
    <xs:sequence minOccurs="0" maxOccurs="unbounded">
        <xs:choice>
            <xs:element name="not" type="notThirdPartyType"/>
            <xs:element name="or" type="orThirdPartyType"/>
            <xs:element name="other" type="otherThirdPartyType"/>
        </xs:choice>
        <xs:element name="varequal" type="varequalThirdPartyType"/>
    </xs:sequence>
</xs:complexType>
