ASP.NET (C#) HTML match help

Using C# I want to extract some data from an HTML code between specified TAGs
For example i want to save the next data into an array
<td class="cote1">4.2062</td>
<td class="cote2">5.345</td>
a[1]="4.2062" , a[2]="5.345"

I've written some functions that save the content of the specified file, but I don't know how to continue.


const string HTML_TAG_PATTERN = "<div class=\"fcstSmTextBox\">([^(<>)]*)</div>";
public string StripHTML(string inputString)
{
return Regex.Replace
(inputString, HTML_TAG_PATTERN, string.Empty);
}

protected void Page_Load(object sender, EventArgs e)
{
String htmlText = file_get_contents("http://www.paginaweb.com");
slideshow.InnerText = StripHTML(htmlText);
}
