cdata noting closing in asp.net xml

Question

I am making a project with asp.net loading xml files

in one of the xml files i have a question and i want to display a picture and flash in different questions.

<![CDATA[<a><img src="Study/1.png"/><a>]]>

that is the code i using in my xml, my problem is its displaying both flash content and images fine but it is not closing the cdata property ie

]]> directly after an image or object.

any ideas?

heres my xml

<?xml version="1.0" encoding="UTF-8"?>
<quiz xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:noNamespaceSchemaLocation="quiz.xsd">
<mchoice>
    <question>For aircraft flying over the high seas, which rules shall be in force?  <![CDATA[<a><img src="Study/1.png"/></a>]]></question>
    <answer>The rules established by the state(s) adjacent to the high seas over flown </answer>
    <answer>The rules established by the state of the operator of the aircraft </answer>
    <answer correct="yes">The rules established by the state of registry of the aircraft </answer>
    <answer>The rules established under the Convention of international civil aviation </answer>
</mchoice>
     </quiz>

here is my schema

            </xs:element>
        </xs:choice>
    </xs:complexType>
</xs:element>
 </xs:schema>

here is my asp.net code for the xml

   Public Shared Function GetQuizDataFromXML(ByVal XMLFileName As String) As ArrayList
    Dim strXmlFilePath As String = XMLFileName
    Dim xDoc As XmlDocument = New XmlDocument()
    xDoc.Load(strXmlFilePath)
    Dim Arl As New ArrayList
    If Not IsNothing(xDoc) AndAlso xDoc.SelectNodes("/quiz/mchoice").Count > 0 Then
        Dim TotalQuestions As Integer = 0
        TotalQuestions = xDoc.SelectNodes("/quiz/mchoice").Count
        For i As Integer = 1 To TotalQuestions
            Dim strXPath As String = ""
            strXPath = "/quiz/mchoice[" & i.ToString() & "]"
            Dim oQ As New Questions
            oQ.QuestionID = i + 1
            oQ.Question = xDoc.SelectSingleNode(strXPath & "/question").InnerXml
            Dim xNodeList As XmlNodeList
            xNodeList = xDoc.SelectNodes(strXPath & "/answer")
            For j As Integer = 0 To xNodeList.Count - 1
                Dim oA As New Answers
                oA.QuestionID = oQ.QuestionID
                oA.Answer = xNodeList.Item(j).InnerText
                oA.AnswerID = j + 1
                Dim xNodeAttr As Object
                'Extract correct answer
                xNodeAttr = xNodeList.Item(j).Attributes.ItemOf("correct")
                oA.IsAnswer = False
                If Not xNodeAttr Is Nothing Then
                    If xNodeAttr.Value = "yes" Then
                        oA.IsAnswer = True
                    End If
                End If
                oQ.Answers.Add(oA)
            Next
            Arl.Add(oQ)
        Next
    End If
    Return Arl
    End Function

Answer 1

Maybe try putting the entire question in the CDATA section as below

<question>
    <![CDATA[For aircraft flying over the high seas, which rules shall be in force? <a><img src="Study/1.png"/></a>]]>
</question>

If that doesn't solve your problem then work through the problem. Start with what works and add complexity until something breaks. For example, modify the <question> tag in this order (the first one should work).

1. <question>This is a test question</question>
2. <question><![CDATA[This is a test question inside a CDATA tag]]></question>
3. <question><![CDATA[This is a test question inside a CDATA tag with a <a>link</a>]]></question>
4. <question><![CDATA[This is a test question inside a CDATA tag with a <a>link</a> and an image <img src="Study/1.png" />]]></question>
5. <question><![CDATA[This is a test question inside a CDATA tag with a linked image <a><img src="Study/1.png" /></a>]]></question>

Answer 2

Could it be because the <a> tag isn't closed ? It should be </a> .

Update

Well, there doesn't seem to be anything wrong with the markup of the CDATA section, as per the W3C specification .

However, since you're using ASP.net, according to this MSDN article , you could try replacing ]]> with ] ]> , and see if that works.
