Question

string x = "I am a hunter, what do i do. <Name> is a good boy. His age is <Age> and a <occupation> of <Institute>. \n\n He is passionate about his <passion> and also a hardworking fellow. <WifeName> is his wife and she is a sweet girl, She loves her husband a lot. Her age is <WifeAge> and <occupation> of <Institute>";

This text dosen’t mean anything. but what i have to do is to replace all “<” with “<b>” and all “>” with “</b>“, all “\n\n” with “<br/>“.

I tried to use :

string y = replace(replace(x,"<","<b>"),">","</b>");

this led me to a devastating result. I think you all can guess, what happened. Now I am searching for a easy and simple solution for this replacement. I wish, I could make this clear.

Answer 1

So if I understand correctly, you use “<” to denote “Start bold” and “>” to denote “End bold”.

Using a composite call to String.Replace obviously isn’t going to work because < is used in the replacement token which is matched by the next call.

One approach is to do the replacement as you encounter it and write it to a new string, like so:

String input = "I am a hunter, what do i do...";
StringBuilder sb = new StringBuilder();
foreach(Char c in input) {

    switch(c) {
        case '<':
            sb.Append("<b>");
            break;
        case '>':
            sb.Append("</b>");
            break;
        case '\r':
            break; // ignore \r characters.
        case '\n':
            sb.Append("<br />");
            break;
        default:
            sb.Append( c );
            break;
    } 
}
return sb.ToString();
