            HTMLDocument htmlPage = new HTMLDocument(@"C:\Dev\Test\AsposeTest\HtmlTest\Sources\page1.html");

            // Concatenate to get the raw string of the page
            // Important: use htmlDocument.DocumentElement.OuterHTML to get htmlPage's HtmlContents(outerHtml)
            string rawPage = htmlPage.Doctype.ToString() + htmlPage.DocumentElement.OuterHTML;
            Console.WriteLine(rawPage);

            // Print Title and inner HTML of file to console
            Console.WriteLine(htmlPage.Title);
            Console.WriteLine(htmlPage.Body.InnerHTML);

            // Get DOM node and set new text in it
            htmlPage.GetElementById("p1").TextContent = "modified paragraph1";

            // Get a collection of specific nodes and traverse
            foreach(var para in htmlPage.Body.GetElementsByTagName("p"))
            {
                Console.WriteLine(para.OuterHTML);
            }
