获取XML节点内容的问题?

[nanfei01055]

请问如何能获取appSettings的整个节点的内容?
Dim configPath As String = Server.MapPath("web.config")
Dim doc As XmlDocument = New XmlDocument()
doc.PreserveWhitespace = True
doc.Load(configPath)
Dim appSettingsXmlNode As XmlNode
appSettingsXmlNode = doc.DocumentElement.SelectSingleNode("//appSettings")
AppSettingsEncrypted.Text = Chr(13) & Chr(10) & appSettingsXmlNode.OuterXml
'这句提示"未将对象引用到实例"


Web.config内容如下:

<?xml version="1.0"?>
<!--

web admin tool to configure settings for your application. Use
the Website->Asp.Net Configuration option in Visual Studio.

</appSettings>
<connectionStrings/>
<system.web>

it enables developers to configure html error pages

<error statusCode="403" redirect="NoAccess.htm"/>
<error statusCode="404" redirect="FileNotFound.htm"/>
</customErrors>
-->
</system.web>
</configuration>

获取appSettings的整个节点的内容：
XmlNodeList a=doc.DocumentElement.GetElementsByTagName("appSettings");
得到一个appsetting的字节点集合。

试下一楼的~

我的问题是要一次性读出appSettins节点下的所有内容,以文本的形式呈现出来,有没有更好的建议,因为XmlNodeList 没有一个类似OuterText的方法,输出整个节点的内容,还请高手支招.

好了,还是自己遍历吧,没有人,分就给上面两位吧

能不能根据节点名称直接读取呢？
