将信息附加到 VB.NET 中的 XML 文件 [英] Appending information to an XML file in VB.NEt

问题描述

<Setting1>
   <SubSetting1>Test1</SubSetting1>
   <SubSetting2>Test2</SubSetting2>
</Setting1>
<Setting2>
   <SubSetting1>Test3</SubSetting1>
   <SubSetting2>Test4</SubSetting2>
</Setting2>

这只是一个引用xml文档的小例子.我正在尝试学习如何附加现有的 xml 文档，而不是写在 xml 标签上.我的实际 xml 文档有更多节点(大约 40 个)，我将所有新值(代替 Test1、Test2、.. 等)放入一个列表中.以正确的顺序，所以我想使用 For 循环来写值.

This is just a small example for reference to an xml document. I am trying to learn how to append an existing xml document, with out writing over the xml tag. My actual xml document has more nodes (about 40) and I am putting all of the new values (in place of Test1, Test2, ..etc) into a list. In the correct order, So I was thinking using a For loop to just write the value.

类似的东西?

Public Sub example (ListofSettings As List(of String))
    Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory)
    Dim myNodes, myChildren As XmlNodeList
    settingsFile.Load(SETTINGS_FILE_PATH)
    myNodes = settingsFile.GetElementsByTagName("Settings1")
For i as Integer = 0 to ListofSettings.count
For Each n As XmlNode In myNodes
        If n.Name = "Settings1" Then
            myChildren = n.ChildNodes
            For Each n1 As XmlNode In myChildren
                Select Case n1.Name
                    Case "SubSetting1"
                        writer.WriteElementString(**DONT WANT TO CHANGE TAG NAME**, ListofSettings.Item(i))
End Select
Next
End if    
Next

推荐答案

使用 Xmldocument.SelectSingleNode 并更改所需节点的 innerXml.有关示例，请参阅 MSDN

Use Xmldocument.SelectSingleNode and change the innerXml of the node that you want. See MSDN for an example
