Appy Html Agility Pack Changes to Web Page

I've used the Html Agility Pack to read/parse HTML elements' values for Coded UI Tests (automated UI testing).

Example:

<html>
  <body>
    <div id='a'> 
      <input name="inp" value="some input"> </input>
    </div>
   </body>
</html>

Grab div with id='a'.

       HtmlAgilityPack.HtmlNode divNode = 
doc.DocumentNode.SelectSingleNode("//div[@id='a']//input[@name='inp']");
Console.WriteLine(divNode.Attributes["value"].Value); // prints out "some input"

I could modify the div's "value" in memory by doing divNode.SetAttribute("value", "new value");.

However, what if I want to actually apply/write this updated value to the web page?

Can I do this with the Html Agility Pack?

The process for modifying a document is something like this:

HtmlDocument doc = new HtmlDocument();
doc.Load("somefile.html");

// modify doc in memory

doc.Save("somefile.html");
