Dim doc As New XmlDocument() 
Dim nodes As XmlNodeList 
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 

將是一種方式。 請注意，如果您已經擁有該節點，則無需重新獲取該節點。
