Question

I need to parse a sentence.
If I find a hash in the sentence, I would like to bold it.

Example : Bonjour #hello Hi => Bonjour #hello Hi

Answer 1

Seems like a good situation for regex

I’d do something like this

boldHashes("Bonjour #hello Hi");

...

private string boldHashes(string str)
{
    return Regex.Replace(str, @"(#\w+)", "<strong>$1</strong>");
}

In this case we’re matching a literal hash # plus a word of any length \w+ and group it between () so we can use the $1 substitions in the Regex.Replace function

Updated jQuery doing the same thing.

Something like:

HTML

<div id="myDiv">Bonjour #Hello hi</div>

jQuery

$('#myDiv').html($('#myDiv').text().replace(/(#\w+)/g, '<strong>$1</strong>'));
