C#

<html xmlns="http://www.w3.org/1999/xhtml" >

I would recommend, that you capture the text only and not the HTML of the element. The text representation would be, "SAMPLE", when HTML representation would depend on the element.

Try HTMLagilityPACK

C#

HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument();

// There are various options, set as needed
htmlDoc.OptionFixNestedTags=true;

// filePath is a path to a file containing the html
htmlDoc.Load(filePath);

// Use:  htmlDoc.LoadHtml(xmlString);  to load from a string (was htmlDoc.LoadXML(xmlString)

// ParseErrors is an ArrayList containing any errors from the Load statement
if (htmlDoc.ParseErrors != null && htmlDoc.ParseErrors.Count() &gt; 0)
{
    // Handle any parse errors as required

}
else
{

    if (htmlDoc.DocumentNode != null)
    {
        HtmlAgilityPack.HtmlNode bodyNode = htmlDoc.DocumentNode.SelectSingleNode("//body");

        if (bodyNode != null)
        {
            // Do something with bodyNode
        }
    }
}
