VB.Net - Remove Text Between Characters

Good Day Experts!

I have quite the little project here today.  I need to remove text between 2 characters and also remove the 2 characters.  This happens 2 times in a line.  It "feels" like it is fairly attainable but I cannot seem to find a solution.  Here is a sample of what I am looking at:

GBP       British Pound       0.6528 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=bdcf3f2cf0&e=a2e1cf5770>        1.5318 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=47712730df&e=a2e1cf5770>       

This is all 1 line in Textpad. I need to remove the text between both sets of <> as well as the <>. So I need to be left with:

GBP       British Pound       0.6528 1.5318

Is this a pretty straight forward endeavor? Can you help me get started with a few tips?

Thanks,

Quick and dirty way... You can find the substring by finding the < and > symbols, then do that two times (one for each link).

I'm sure there's a neater and more elegant way, I'm just typing this out of the top of my head.

An implementation of a quick and dirty method:
Module Module1
	Sub Main()
		Dim gbp = "GBP       British Pound       0.6528 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=bdcf3f2cf0&e=a2e1cf5770>        1.5318 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=47712730df&e=a2e1cf5770>"
		Dim index As Integer = gbp.IndexOf("<")
		While (index <> -1)
			If gbp.IndexOf(">", index) <> -1 Then
				gbp = String.Format("{0}{1}", gbp.Substring(0, index), gbp.Substring(gbp.IndexOf(">", index) + 1))
			End If
			index = gbp.IndexOf("<", index + 1)
		End While
		Console.WriteLine(gbp)
		Console.ReadLine()
	End Sub
End Module

Open in new window

Produces the following output -Capture.JPG-saige-

Hi jimbo99999;

This should do what you need.
Imports System.Text.RegularExpressions


'' Test Data
Dim data = "GBP       British Pound       0.6528 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=bdcf3f2cf0&e=a2e1cf5770>        1.5318 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=47712730df&e=a2e1cf5770>      "
'' Remove URL's from the string and trim any white spaces from the start and end
data = Regex.Replace(data, "<http[^>]*>\s*", String.Empty).Trim()

Open in new window


Resulting string.
GBP       British Pound       0.6528 1.5318

A change to the substring code presented above:
Module Module1
	Sub Main()
		Dim gbp = "GBP       British Pound       0.6528 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=bdcf3f2cf0&e=a2e1cf5770>        1.5318 <http://exchangerates.us2.list-manage2.com/track/click?u=216e81aed0649ca9d1a45cc41&id=47712730df&e=a2e1cf5770>"
		Dim index As Integer = gbp.IndexOf("<")
		While (index <> -1)
			If gbp.IndexOf(">", index) <> -1 Then
				gbp = String.Format("{0}{1}", gbp.Substring(0, index), gbp.Substring(gbp.IndexOf(">", index) + 1))
			End If
			' Have to ensure that the index does not surpass the length
			index = gbp.IndexOf("<", If(index + 1 > gbp.Length, 0, index + 1)) 
		End While
		Console.WriteLine(gbp)
		Console.ReadLine()
	End Sub
End Module

Open in new window


Otherwise the output is the same.

Regex could probably handle this well, but I'm not very versed in that.  I'd simply do this:

(assuming that text is stored in a variable called conversion:
Dim iLeftBracketPosn As Integer
Dim iRightBracketPosn As Integer 
Do
   iLeftBracketPosn = conversion.IndexOf("<")
   iRightBracketPosn = conversion.IndexOf(">")
   If iLeftBracketPosn < 0 Or iRightBracketPosn < 0 Then
      Exit Do
   End If
   conversion = conversion.Substring(0, iLeftBracketPosn - 1) & conversion.Substring(iRightBracketPosn + 1)
Loop

Open in new window


(Do a quick check on that to ensure that the left and right brackets are removed and the adjacent text is intact; otherwise you may need to +/- 1 to fix it.)

If you are attempting to do this wholly in TextPad, then Fernando's regex should work there to. Just be sure to check the "Regular expression" box and leave the Replace box blank in Find/Replace.

Thanks everyone for the help.  Lionking spurred my thought process and went went down the path of that suggestion.  I liked the other ways for my toolbox.

Thanks again,
