The preceding examples of getting HTML code on the page have provided a lot of examples.
The following code uses a regular expression to retrieve HTML content
Regex regex1 = new Regex (this. NameKey, RegexOptions. Singleline | RegexOptions. IgnoreCase );
MatchCollection collection1 = regex1.Matches (this. Arthur TML );
If (collection1.Count> 0)
{
Result = collection1 [0]. Result ("$ {title }");
}
