Dim doc As New XmlDocument()

doc.Load(FILE_NAME)

nodes = doc.SelectNodes("/details")
Dim node As XmlNode

For Each node In nodes

    Dim nodeid As XmlNode = node.SelectSingleNode("id")
    If nodeid IsNot Nothing Then
        MsgBox(nodeid.InnerText)
    End If
    Dim nodeimdb_id As XmlNode = node.SelectSingleNode("title")
    If nodeimdb_id IsNot Nothing Then
        MsgBox(nodeimdb_id.InnerText)
    End If

    Dim genreNodes As XmlNodeList = node.SelectNodes("genre")
    For each genreNode in genreNodes
        MsgBox(genreNode.InnerText)
    Next

Next

将是一种方式。注意，看到你已经有了节点，不需要再次获取它。
