Hello @asad.ali ,
The same behaviour is observed with version 24.1.
The sample code is below, it worked with the version 22 of Aspose.HTML


			Aspose.Html.License lic = new Aspose.Html.License();
			using ( Stream str = File.OpenRead(licenceFileName) ) {
				lic.SetLicense(str);
			}

			string testHTML = @"<!DOCTYPE HTML>
<html>
	<body onclick=""doSomething()"">
	</body>
</html>";
			using HTMLDocument hDoc = new HTMLDocument(testHTML, ".");

			const string onClickAttrName = "onclick";

			foreach ( Element el in hDoc.DocumentElement.QuerySelectorAll("*") ) {
				string onClickVal = el.GetAttribute(onClickAttrName);
				if ( !string.IsNullOrEmpty(onClickVal) ) {
					el.RemoveAttribute(onClickAttrName);
				}
			}
		}
