我想解析出其中的某个节点，发现返回的都是空值

比如 gGr:vsize>176.149</egGr:vsize>和    <egGr:hsize>290.068</egGr:hsize>

这几个例子我都参考过了 

Dim dlg As new OpenFileDialog
If dlg.ShowDialog = DialogResult.OK Then
    \'\'Dim txt As String = FileSys.ReadAllText(dlg.FileName, Encoding.Default)
    
    
    \'Dim xmlDoc As New System.XML.XmlDocument
    \'xmlDoc.Load(dlg.FileName)
    \'Dim ndList  = xmlDoc.GetElementsByTagName("egGr:vsize")
    \'For i As Integer = 0 To ndList.count - 1
        \'\'msgbox(ndlist(i).Attributes("egGr:vsize").value)
        \'output.show(i)
        \'output.show(ndlist(i).value)
    \'Next
\'\'output.show(xmlDoc.GetElementsByTagName("egGr:vsize")(0).value)

Dim ret As String = FileSys.ReadAllText(dlg.FileName, encoding.default)
Dim xo As XObject = XObject.Parse(ret)
\'\'output.show(xo.ToString())
Dim jo As JObject = JObject.Parse(xo.Tostring)
Dim ja As JArray = jo("rdf:Description")
For i As Integer = 0 To ja.Count - 1
   Output.Show(ja(i).ToString)
Next
\'Output.Show(jo("rdf:Description"))
output.show(xo("egGr:vresolution"))
End If

Dim txt As String = FileSys.ReadAllText("D:\\问题\\test.xml", Encoding.Default)
Dim xmlDoc As New System.XML.XmlDocument
xmlDoc.Loadxml(txt)
Dim ndList  = xmlDoc.GetElementsByTagName("egGr:vsize")
For i As Integer = 0 To ndList.count - 1
    output.show(ndlist(i).InnerXml)
Next


Dim txt As String = FileSys.ReadAllText("D:\\问题\\test.xml", Encoding.Default)
Dim xmlDoc As New System.XML.XmlDocument
xmlDoc.Loadxml(txt)
Dim ndList  = xmlDoc.GetElementsByTagName("rdf:Description")
For i As Integer = 0 To ndList.count - 1
    For Each n As System.XML.XmlNode In ndlist(i).childNodes
        output.show(n.Name & " = " & n.InnerText)
    Next
Next
