Parse HTML page and capture contents

Here I show a simple class that receives the HTML string and then extracts all the links and their text into structs. It is fairly fast, but I offer some optimization tips further down. It would be better to use a class.

using System; 
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;

namespace PSC
public class Finder
public struct LinkItem
public string Href;
public string Text;

public override string ToString()
return Href + "\n\t" + Text;

public class LinkFinder
public static List<LinkItem> Find(string file)
List<LinkItem> list = new List<LinkItem>();
// 1.
// Find all matches in file. MatchCollection
m1 = Regex.Matches(file, @"(<a.*?>.*?</a>)", RegexOptions.Singleline);

// 2.
// Loop over each match.
foreach (Match m in m1)
string value = m.Groups[1].Value;
LinkItem i = new LinkItem();

// 3.
// Get href attribute.
Match m2 = Regex.Match(value, @"href=\""(.*?)\""", RegexOptions.Singleline);
if (m2.Success)
i.Href = m2.Groups[1].Value;

// 4.
// Remove inner tags from text.
string t = Regex.Replace(value, @"
\s*<.*?>\s*", "", RegexOptions.Singleline);
i.Text = t;
return list;
