Weather board, how to get html data.

Hi All,

I am going to create a personal weather board.

It is easy to show the picutre on website ( just link the picture to
picturesbox's properties )

but I dont' know how to add some other text near by..

for example:

I can get the weather icon, but I don't know how to get the description
text...

What should I do?

Best regards,
Boki.

Depends if you are talking about text adjacent to the picture or Alernate
text, iether way you will need to scrape the site and parse the text. Seach
for web scraping on google.

Don't know where you are, but if in the U.S. the NWS has several XML
feeds which make it very easy to use directly in a app. Here is a
current observation example:

I use InStr() to search WebBrowser1.DocumentText, could you please
advice how to search the XML data tag? ( a better way than InStr() )..

Best regards,
Boki.

Boki,

To read an unknown xml document is this probably the easiest method

I hope this helps,

As noted in other responses, you would want to read the XML elements
directly (XML Reader Class). Has nothing to do with a WebBrowser.

Hi,

            I have used the yahoo weather rss for this.   They have a
weather sticker embedded in it. The address for the rss feed has a
querystring for getting the weather. In the us use your zipcode for getting
the weather. This example requires a textbox (txtZip) for entering in a
zipcode to get the weather for, webbrowser control to display the weather
sticker, and a button (btnGetWeather).

    Private Sub btnGetWeather_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles btnGetWeather.Click
        Dim sr As IO.StreamReader
        Dim wc As New System.Net.WebClient
        Dim strUrl As String
        Dim strOut As String = ""
        strUrl =
String.Format("http://xml.weather.yahoo.com/forecastrss?p={0}", txtZip.Text)

        Try
            sr = New IO.StreamReader(wc.OpenRead(strUrl))
            Dim strHtml As String = sr.ReadToEnd
            Dim x As Integer = strHtml.IndexOf("<img src")
            Dim y As Integer = strHtml.IndexOf(")<br/>")
            strOut = strHtml.Substring(x, y - x + 6)
            sr.Close()
        Catch
            strOut = "<h1>Error getting weather</h1>"
        Finally
            WebBrowser1.DocumentText = strOut
        End Try
    End Sub
