Question

I have the following string , i tried many many regex to remove comma between a tag text, but not found any regex for removing comma between a tag text. I want that , whenever text inside a tag has comma ,then will be replace by empty string.

<a href="#" class="main">Getty Center, Restaurant at the</a>

i have tried this regex but it is not working, here input is string that contains html.

input = Regex.Replace(input, @"<a(\s+[^>]*)?>[^\w\s]</a(\s+[^>]*)?>", "");

Please help me out. Thank You

You can use the Regex to find and modify the content of the tag like so.

var input = "<a href=\"#\" class=\"main\">Getty Center, Restaurant at the</a>";
var regex = new Regex(@"<a[^>]*>(?<content>.*?)</a[^>]*>",
                      RegexOptions.Singleline);
var match = regex.Match(input);
while (match.Success) {
    var group = match.Groups["content"];
    input = input.Substring(0, group.Index)
            + group.Value.Replace(",", "")
            + input.Substring(group.Index + group.Length);
    match = regex.Match(input, group.Index);
};

The loop is in place to catch multiple tags in the same string. The Regex however is fairly naive. It will mess with tags nested inside the A tag, and will parse incorrectly if a > is in any of the attributes. (Though that would probably be bad HTML anyway.) A proper HTML parser is recommended for this reason.
