Question

我正在使用asp.net加载xml文件制作项目

在其中一个xml文件中我有一个问题，我想在不同的问题中显示图片和flash。

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

这是我在我的xml中使用的代码，我的问题是它显示flash内容和图像都很好但是它没有关闭cdata属性，即

]]＆GT; 直接在图像或对象之后。

任何想法？

继承人我的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>

这是我的架构

这是我的xml

的asp.net代码

   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)

            Arl.Add(oQ)
        Next

    Return Arl
    End Function

Answer 1

也许可以尝试将整个问题放在CDATA部分中，如下所示

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

如果这不能解决您的问题，那么解决问题。从有效的方法开始，增加复杂性直到出现问题。例如，按此顺序修改<question>标记（第一个标记应该有效）。

<question>This is a test question</question>
<question><![CDATA[This is a test question inside a CDATA tag]]></question>
<question><![CDATA[This is a test question inside a CDATA tag with a <a>link</a>]]></question>
<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>
<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

可能是因为<a>标签未关闭？它应该是</a>。

<强>更新

嗯，根据W3C specification，CDATA部分的标记似乎没有任何问题。

但是，由于您使用的是ASP.net，根据this MSDN article，您可以尝试将]]>替换为] ]>，看看是否有效。

cdata注意到在asp.net xml中关闭
