Update XML file.

[tassa]

Hello,

I'm trying to enter new information in a specific node in a xml file. This is the structure of the xml file:

<Root>

<Title 1>

<Title 2></Title 2>

</Title 1>

</Root>

How would I update <Title 2></Title 2> field?

Thanks in advance.

This was created in VS2008, should work just fine in VS2010.

Create a file called Books.xml in the executable folder.

<?xml version="1.0" encoding="utf-8"?>
<Root>
    <Titles>
        <Title Name="1">I love .NET</Title>
        <Title Name="2">I Love Delphi</Title>
    </Titles>
</Root>

Add this code

    Private Sub UpdateXmlItem()
        Dim Doc = XDocument.Load("Books.xml")
        Dim query = From items In Doc...<Title> Where items.@Name = "2"

        If query.Value = "Bye Bye Delphi" Then
            Console.WriteLine("You already said good bye")
        Else
            Console.WriteLine(query.Value)
            query.Value = "Bye Bye Delphi"

            Console.WriteLine(query.Value)
            Doc.Save("Books.xml")
        End If

    End Sub
