[RESOLVED] Need some XML help.

[formlesstree4]

Basically, I have an XML file that will have something like this in it:

<question="What happened in 1492?">
	<answer=true>Columbus sailed the Ocean blue!</answer>
	<answer=false>I divided by Zero!</answer>
	<answer=false>Muffins</answer>
	<answer=false>Programming</answer>
</question>

Similar questions (with better answers) will also be there. I will have 5 files, each file having 10 question groups each. I have no clue how to read this properly, or how to tell what the answers are! I would also need help writing these too.

XML was never my strongpoint, so any pointers/tips/tricks/code examples would be lovely!

Are you looking for something simple like this?

try this. it's hardcoded with a modified version (i had to fix the xml) of your xml, but can be easily changed to open + use an external xml file:

Hey .paul., thanks for that...I hate to bother you with this though. I did fail to mention I was restricted to 2.0, since I don't know if the school computers are updated enough. If there is a possibility of using XmlTextReader possibly instead of LINQ, I'll hop on that.

@sapator, I'll look into it.

I fiddled around with XmlDocument, and..now I have this:

System.Xml.XmlException was unhandled
  LineNumber=1
  LinePosition=1
  Message=Data at the root level is invalid. Line 1, position 1.
  Source=System.Xml
  SourceUri=""

Here's the code I'm using:

Public Sub New(ByVal questions As String)
        Dim reader As New XmlDocument With {.PreserveWhitespace = True}
        reader.LoadXml(questions) '<- errors right here.

        Dim QuestionXmlList As XmlNodeList = reader.SelectNodes("question")
        If QuestionXmlList.Count > 0 Then

            For Each item As XmlNode In QuestionXmlList
                'Setup a loop for each <question> area.
                Dim NQ As New QuestionData
                With item
                    NQ.Question = .Item("ask").InnerText
                    NQ.Answer(1) = .Item("answer1").InnerText
                    NQ.Answer(2) = .Item("answer2").InnerText
                    NQ.Answer(3) = .Item("answer3").InnerText
                    NQ.Answer(4) = .Item("answer4").InnerText
                    NQ.CorrectAnswer = CInt(.Item("correct").InnerText)
                End With
                QuestionList.Add(NQ)
            Next
        End If
    End Sub

And this is the XML I'm using....

<question>
	<ask>What important event happened in 1492?</ask>
	<answer1>Columbus sailed the Ocean blue!</answer1>
	<answer2>I divided by Zero!</answer2>
	<answer3>Muffins</answer3>
	<answer4>Programming</answer4>
	<correct>1</correct>
</question>

EDIT: Scratch that entire mess. I changed it to just Load() instead of LoadXml....no more errors and it reads it perfectly. I'm gonna mark this as resolved.
