LINQ To XML And RSS

前陣子上課時展示過一個例子,以LINQ To XML來讀取RSS Feed,

當時我是使用離線的XML,最近有空把他改為直接讀取網路上的RSS.

0 1 Sub LoadRSS() LoadRSS()
02 Dim request As System.Net.WebRequest = _
03 System.Net.WebRequest.Create("http://www.dotblogs.com.tw/code6421/category/1530.aspx/rss")
04 Dim response As System.Net.HttpWebResponse = CType(request.GetResponse(), System.Net.HttpWebResponse)
05 Dim dataStream As System.IO.Stream = response.GetResponseStream()
06 Dim reader As System.IO.StreamReader = New System.IO.StreamReader(dataStream)
07 Using (reader)
08 Dim xmlDoc = XDocument.Load(reader)
09 Dim result = From s1 In xmlDoc...<item> Select s1
10
11
12 For Each item In result
13 Console.WriteLine(item.<title>.Value)
14 Next
15 Console.ReadLine()
16 End Using
17 End Sub

此例子使用VB.NET 2008寫成,如你所見,VB.NET於XML處理時,比C#來得簡潔.
