How to remove a special characters from the parsed string

Question

I am parsing a price of some items from a website. However, I am getting some irrelevant special characters before the string. How do I remove those characters and the string that I want?

I am getting

\n                \n                    \n                    \n                \n\n                \n                    \n                    \n                        AMD YD2600BBAFBOX 3.9GHz Socket AM4 Processor

and    17,975.00    17,975.00

However, I have used Replace method to replaced the unwanted special characters from the string

itemName = itemNameNode.InnerText.Replace("\n", "");
itemPrice = itemPriceNode.InnerText.Replace("                      ", "Current price:");

Still I am not getting the expected result. I am getting the result as

Answer 1

Instead of doing a replace on the newlines for your itemName string, you could simply use String.Trim . Trim removes any leading or trailing characters on the string that return true to a char.IsWhiteSpace call, of which a new line character is included.

var x = "\n   Hello   \n";

Console.WriteLine("-");
Console.WriteLine(x);
Console.WriteLine("-");
/* Output:
-

   Hello   

-
*/

Console.WriteLine("-");
Console.WriteLine(x.Trim());
Console.WriteLine("-");
/* Output:
-
Hello
-
*/

First, I'd try it like this.

itemName = itemNameNode.InnerText.Trim();
itemPrice = itemPriceNode.InnerText.Trim().Replace("  ", "Current price:");

How about using Trim() before using Replace()

I hope it helps you.
