manuplate string in a specific tag in html file

darma teja

Hi,

I have an html file, In which i have many "a" tags.

example: .com">Visit W3Schools.com!

I want to replace back space with "-" and the final output will be like this www.w2schools-.com
.com">Visit W3Schools.com!

Thanks

Darma

All my code does is to replace back-space characters (ASCII 8) with hyphens.

It doesn't change 'normal' space characters (ASCII 32) at all.

Are you saying that you want to replace normal spaces within href only with hyphens?

If so, then it can be done using regular expressions as follows:

using System.IO;
using System.Text.RegularExpressions;

// ...

string html = File.ReadAllText("darma.htm");
char[] chars = html.ToCharArray();
string regExp = @"";
MatchCollection mc = Regex.Matches(html, regExp);
foreach(Match m in mc)
{
int index = m.Groups[1].Index;
int length = m.Groups[1].Length;
for(int i = index; i < index + length; i++)
{
if(chars[i] == ' ') chars[i] = '-';
}
}
html = new string(chars);
File.WriteAllText("darma.htm", html);

Hi Vulpes,

Thank you very much for the reply.

Actually when I did with this code, It removes all black spaces in html file.

But I want to remove only blank spaces in href only.

It seems odd to have backspace characters (ASCII 8) in an HTML file but, if that's what they are, then you may be able to replace them all with hyphens using a simple string replace:

using System.IO;

// ...

string html = File.ReadAllText("darma.htm");
html = html.Replace('\b', '-');
File.WriteAllText("darma.htm", html);
