Remove HTML from string with regular expression
It's really simple to do that with just a few lines of code. Here is how to:
Private Function RemoveHTML(ByVal str As String) As String
Dim RegExp As String = "<[^>]*>"
Dim R As New Regex(RegExp)
Return R.Replace(str, " ")
End Function
And you can get the "clear" string for your label control (for example):
Label1.Text = RemoveHTML(TextBox1.Text)
Getting web file content from url with ASP.NET 3.5
Here's how you could get page or file content with help of webclient class and use it for example to get the forex rates or regional weather forecast from diferent page and show it to yours:
First we need to import the required name spaces:
Imports System.Net
Imports System.IO
Second there we go with our method:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim client As New WebClient
Dim sr As StreamReader = New StreamReader(client.OpenRead("http://www.snb-bg.com/test.txt"), System.Text.Encoding.Default(), False)
Dim sb As New StringBuilder
Do While sr.Peek >= 0
sb.Append(sr.ReadLine())
Loop
Label1.Text = sb.ToString()
client.Dispose()
sr.Dispose()
sr.Close()
End Sub
I think this example is quite easy and don't need more explanation, but in case you need please feel free to send me feedback.
