Remove 
 from String in .net

Question

Hello,

I have a string with &#xA in it the regex:

• string value = Regex.Replace(textNode.Value, @"\s+", " ");

• value = value.Replace(" ", "");

• value = Regex.Replace(value, @"\&#xA", "");

• value = value.Replace("\n", "");

didn't remove it.

How do I go about removing &#xA?

Note: It did function as a newline when added to a textbox.

Thanks.

Answer 1

Regex is not necessary for simple string manipulation in .Net. System.String has a Replace method.

VB

myString = myString.Replace("&#xA", "")

C#

myString = myString.Replace("&#xA", "");

However, is &#xA is not an actual string, but a byte, (The way 1 is a number, but "1" is a string) the code would be different. But as the question was asked, the above would be the answer.

Based on the fact that your code sample contained "textNode.Value" I'm gussing you're parsing XML. If so, your question has already been asked and answered here:

Answer 2

Escape the ampersand in your regex

string s = "hello &#xA there";

Console.WriteLine(Regex.Replace(s, @"\&#xA", ""));
//or more simply:
Console.WriteLine(s.Replace("&#xA", ""));

&#xA is a new line character, if I recall correctly. If David Stratton's edited answer didn't do it for you, try this:

myString = myString.Replace("\n", "");
