Question

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>

Here is the fragment of xsd that valide the xml

The element ‘conditionvar’ in namespace ‘test.xsd’ has invalid child element ‘varequal’ in namespace ‘test.xsd’. List of possible elements expected: ‘not’.
The element cannot contain white space. Content model is empty.

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

Found the answer:

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

 <!-- ****************** -->
 <!-- ** conditionvar ** -->
  <!-- ****************** -->
 <xs:complexType name="conditionvarThirdPartyType">
 <xs:sequence minOccurs="0" maxOccurs="unbounded">
  <xs:choice  minOccurs="0" maxOccurs="unbounded">
    <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"   minOccurs="0" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>

Thanks for your help.

Answer 1

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.

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>
