使用VB.net 2008编写XML的好例子 [英] Whats a Good Example to Write XML using VB.net 2008

问题描述

使用此示例，我将如何使用此示例更新XML文件:

Using this example how would I go about updating an XML file using this example:

<foo>
   <n1>
       <s1></s1>
       <s2></s2>
       <s3></s3>
   </n1>
   <n1>
       <s1></s1>
       <s2></s2>
       <s3></s3>
   </n1>
</foo>

我可以整天阅读它，但是对于我一生来说，我似乎无法将其写成这种格式.

I Can read from it all day long but for the life of me I cannot seem to write it back into that format.

推荐答案

直接方法:

' to create the XmlDocument... '
Dim xmlDoc As New Xml.XmlDocument

Dim fooElement As Xml.XmlElement = xmlDoc.CreateElement("foo")
xmlDoc.AppendChild(fooElement)

Dim n1Element As Xml.XmlElement = xmlDoc.CreateElement("n1")
For Each n1ChildName As String In New String() {"s1", "s2", "s3"}
    Dim childElement As Xml.XmlElement = xmlDoc.CreateElement(n1ChildName)
    n1Element.AppendChild(childElement)
Next

fooElement.AppendChild(n1Element)
fooElement.AppendChild(n1Element.CloneNode(deep:=True))

' to update the XmlDocument (simple example)... '
Dim s1Element As Xml.XmlElement = xmlDoc.SelectSingleNode("foo/n1/s1")
If Not s1Element Is Nothing Then s1Element.InnerText = "some value"
