Question: I have a method that returns a string in the following format:

```
string tableTag = "<th><a href="Boot_53.html">135 Boot</a></th>"

```

I want to get the value of the `href` attribute and store it into another string called `link`:

```
string link = "Boot_53.html"

```

In other words, `link` should be assigned the `href` attribute in the string. How can I accomplish that?

Answer: 
You could use an HTML parser such as [`HTML agility pack`](http://htmlagilitypack.codeplex.com/) to parse the input HTML and extract the information you are looking for:

```
using HtmlAgilityPack;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

class Program
{
    static void Main(string[] args)
    {
        var doc = new HtmlDocument();
        string tableTag = "<th><a href=\"Boot_53.html\">135 Boot</a></th>";
        doc.LoadHtml(tableTag);

        var anchor = doc.DocumentNode.SelectSingleNode("//a");
        if (anchor != null)
        {
            string link = anchor.Attributes["href"].Value;
            Console.WriteLine(link);
        }
    }
}

```
You can use [AngleSharp](https://anglesharp.github.io/) as an alternative to HtmlAgilityPack:

```
var context = BrowsingContext.New(Configuration.Default);

string tableTag = "<th><a href=\"Boot_53.html\">135 Boot</a></th>";

var document = await context.OpenAsync(req => req.Content(tableTag));

var anchor = document.All.FirstOrDefault(x => x.LocalName == "a");
if (anchor != null)
{
    string link = anchor.GetAttribute("href"); // "Boot_53.html"
}

```
