只有根的空白XML

Question

嗨，我试图在vb.net中错误处理空白xml文件，原始xml看起来像这样。

<settings>
   <connection = "aaaa" user = "bbbb" perm = "bgshs"
</settings>

问题是，我试图检查xml是否有根只有空白，然后把它发送到其他地方。如

<settings>
</settings>

Answer 1

试试这个

Imports System.Xml
Imports System.Xml.Linq
Module Module1
    Sub Main()
        Dim input As String = "<settings></settings>"
        Dim element As XElement = XElement.Parse(Input)
        If Not element.HasElements Then
            Console.WriteLine("Has no elements")
            Console.ReadLine()
        End If
    End Sub
End Module
