Try with SaxParser

Hello mkvidyashankar,

THEORETICALLY, something like this should work (have not tested it).
However, the SaxParser might have problems with the "<yweather:" tag, in which
event you would need to parse the feed manually using String functions
and download the feed using GetString():

Dim feed as String
feed = Response.GetString("UTF8")
in Sub HttpClient1_ResponseSuccess (Response As HttpResponse, TaskId As Int)

Sub Process_Globals
   Dim Parser As SaxParser
   Dim HttpClient1 As HttpClient
   Dim wm as String
End Sub

Sub Activity_Create(FirstTime As Boolean)
    If FirstTime Then
   Parser.Initialize
   HttpClient1.Initialize("HttpClient1")
    End If
    Request.InitializeGet("http://..................") 'your feed URL here
    If HttpClient1.Execute(Request, 1) = False Then Return
End Sub

Sub HttpClient1_ResponseSuccess (Response As HttpResponse, TaskId As Int)
   Dim Result As InputStream
   Result = Response.GetInputStream
   Parser.Parse(Result, "Parser")
   Result.Close
End Sub

Sub Parser_EndElement (Uri As String, Name As String, Text As StringBuilder)
   If Parser.Parents.IndexOf("item") > -1 Then
      If Name = "yweather" Then                [COLOR="Red"]'error likely here[/COLOR]
          wm = wm & Text.ToString & CRLF
      Else If Name = "description" Then
          wm = wm & Text.ToString
      End if
   End If
End Sub

It should be parsable with the Sax parser.
If it doesn't work for, please upload a text file with the complete RSS feed.

Hi erel

Here is the text file

 

[Erel]

Have you tried alfcen solution? Did it work?

 

[mkvidyashankar]

No it did not worked !

 

[Erel]

In what way isn't it working? I tried it and it fetches the description node correctly.
The condition node should be extracted from the attributes:

Sub Parser_StartElement (Uri As String, Name As String, Attributes As Attributes)
   If name = "condition" Then
      For i = 0 To Attributes.Size - 1
         Log("name=" & Attributes.GetName(i))
         Log("value=" & Attributes.GetValue(i))
      Next
   End If
End Sub
