automating the w3c css test with selenium

1.Create a table where url/body of css file is stored
2.Then fetch data from query
3.In a for loop send call to W3CCSSTest(selenium,dr)


public void W3CCSSTest(ISelenium selenium, DataRow dr)
{
string sql = "";
string cols = "";
string nexturl="";
verificationErrors = new StringBuilder("");

selenium.Open("/");


Thread.Sleep(2000);
try
{

if (dr["type"].ToString() == "U") // if url
{

selenium.Open("http://jigsaw.w3.org/css-validator/");
selenium.Type("uri", dr["BodyUrl"].ToString());
selenium.Click("link=More Options");
Thread.Sleep(1000);
selenium.Select("profile_uri", "label=No special profile");
selenium.Click("//fieldset[@id='validate-by-uri']/form/p[3]/label/a/span");
nexturl = "http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fjigsaw.w3.org%2Fcss-validator%2F&profile=none&usermedium=all&warning=1&lang=en";
}
if (dr["type"].ToString() == "B") //if body
{
selenium.Open("http://jigsaw.w3.org/css-validator/");
selenium.Click("link=By direct input");
selenium.Type("text", dr["BodyUrl"].ToString());
Thread.Sleep(1000);
selenium.Select("profile_input", "label=No special profile");
selenium.Click("//fieldset[@id='validate-by-input']/form/p[3]/label/a/span");
nexturl = "http://validator.w3.org/check?uri=http%3A%2F%2Fvalidator.w3.org%2F&charset=%28detect+automatically%29&doctype=HTML+4.01+Transitional&group=0&ss=1&No200=1";
}
Thread.Sleep(3000);

if (selenium.IsTextPresent("Congratulations!"))
{
verificationErrors.Append("pass,");
CreatedScreenShot = Utilities.SeleniumScreenShot(selenium, ScriptAndDirName, dr["Rid"].ToString() + "W3C_CSS_PASS");
DatabaseClass.LogDataInResultTable(ScriptAndDirName, TableName, Convert.ToInt16(dr["Rid"].ToString()), "P", CreatedScreenShot, Convert.ToString(verificationErrors), dr["owner"].ToString());
}

if (selenium.IsTextPresent("Sorry! We found the following errors"))
{
verificationErrors.Append("fail,");
CreatedScreenShot = Utilities.SeleniumScreenShot(selenium, ScriptAndDirName, dr["Rid"].ToString() + "W3C_CSS_FAIL");
DatabaseClass.LogDataInResultTable(ScriptAndDirName, TableName, Convert.ToInt16(dr["Rid"].ToString()), "F", CreatedScreenShot, Convert.ToString(verificationErrors), dr["owner"].ToString());
