Extract a web site shortcut icon (favicon)

Hello everyone! I really need your help: I have a program which displays some web pages. What I'm trying to do is to extract the linktag with the rel parameter set to "shortcut icon" from the web page's source and show in a text box its href parameter. For example, if the following line is in a web page's source:

Code:

---

<link rel="shortcut icon" href="http://s.ytimg.com/yt/favicon-refresh-vfldLzJxy.ico" type="image/x-icon">

---

then it should write the following in the text box: http://s.ytimg.com/yt/favicon-refresh-vfldLzJxy.ico (the example above is from the www.youtube.com web site). I use the Microsoft Internet Controls (WebBrowser1) to display web pages. Can you halp me with this?
Thanks in advance,
