            InitializeComponent();
        }

        //public MatchCollection Matches(string input);

        public static string StringStrip(string Text)
        {
            Text = Regex.Replace(Text, "<.*?>", string.Empty);

            return Text;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //används för att bygga en sträng från ström
            StringBuilder sb = new StringBuilder();

            byte[] buf = new byte[8192];

            HttpWebRequest request = (HttpWebRequest)
                WebRequest.Create("http://rankswebowl.svenskidrott.se/Query.aspx?QueryParm=100|QueryRankPoints DESC,QueryAverage DESC,QueryPlace DESC||1|||||'26768-07'|||||||");
            
            HttpWebResponse response = (HttpWebResponse)
                requset.GetResponse();

            Steam resStream = response.GetResponseStream();

            string tempString = null;
            int count = 0;

            do
            {
                count = resStream.Read(buf, 0, buf.Length);

                if (count != 0)
                {
                    tempString = Encoding.UTF8.GetString(buf, 0, count);
                    sb.Append(tempString);
                }
            }
            while (count > 0);
            {
