How do I get the value from a specific node in an XML file?
linq, vb.net, xml, xml-serialization, xpath
Solution
You can also use XPath to read the element's value:
Dim doc As XmlDocument = New XmlDocument()
doc.Load("C:\members.xml")
Dim kills As String = doc.SelectNode("Tabel/Member[Naam='Ghostbullet93']/Kills").InnerText
If, however, you intend to load and use all the data, it would be far easier to use serialization. To do that, you first need to create classes that mimic the XML structure (for simplicity sake I'll just use public string fields, but it would be better to use properties):
Public Class Member
Public Naam As String
Public Kills As Integer
Public Deaths As Integer
Public KD As Integer
End Class
Public Class Tabel
<XmlElement("Member")> _
Public Members As List(Of Member)
End Class
Then deserialize the XML like this:
Dim serializer As XmlSerializer = New XmlSerializer(GetType(Tabel))
Dim tabel As Tabel = CType(serializer.Deserialize(File.OpenRead("C:\members.xml")), Tabel)
For Each member As Member in tabel
Dim kills As Integer = member.Kills
Next
Problem
From this XML code: ``` <?xml version="1.0" encoding="utf-8"?> <Tabel> <Member> <Naam>Cruciatum</Naam> <Kills>1000</Kills> <Deaths>10</Deaths> <KD>100</KD> </Member> <Member> <Naam>Ghostbullet93</Naam> <Kills>10</Kills> <Deaths>1</Deaths> <KD>10</KD> </Member> </Tabel> ``` How can I get (for example) the 10 next to `<Kills>` ? I've tried multiple things without any success. One of the ideas I had was using this code: ``` Dim doc = XDocument.Load("C:\members.xml") Dim members = From m In doc.Element("Tabel").Elements("Member") Select naam = m.Element("Naam").Value For Each member In members lstmembers.Items.Add(member) Next ``` But I can't figure out how to edit that snippet to work with what I need it to do now. (The above code works perfectly for where it's used.)
