Question

I have a rather nasty string on form:

<aa>b</aa><ccc>ddd</ccc>

and i’d like all the tags to be exchanged for <td> so we’ll see this:

<td>b</td><td>ddd</td>

How can i do that in C#? I’m guessing regexp but it’s been a while ago so i’ll need some help.

Answer 1

var startTag = new Regex(@"\<(?<tag>\w+)\s*\>");
var endTag = new Regex(@"\<\/\w+\>");
var result = startTag.Replace("<aa>b</aa><ccc>ddd</ccc>", "<td class=\"${tag}\">");
result = endTag.Replace(result,"</td>");
