两种方法：
其一，使用 SelectNodes 的方法；以下例子为使用此方法的处理。
其二，使用 XQuery 的方法。
''' <summary>
''' 从 XML 文件中取得对应ID 的语言值
''' </summary>
''' <param name="textID">输入的ID</param>
''' <returns></returns>
''' <remarks></remarks>
Private Shared Function GetLanguageTextfromXML(ByVal textID As String) As LangText
Dim _return As LangText = Nothing
Try
If Not IsNothing(_xmlDoc) Then
Dim nodeList As XmlNodeList
nodeList = _xmlDoc.SelectNodes("//item[@text_id='" & textID.ToLower & "']")
Dim node As XmlNode
Dim _languageID As String '= IIf(Language = eLanguage.English, "ENG", "CHN")
For Each node In nodeList
_languageID = node.Attributes("language").Value.ToUpper
Select Case _languageID
Case "ENG"
