Hi Bob

Take a look at the comment above yours. Lennart points out, that Google may have changed their HTML markup lately – which have broken my code.

Hope you’ll get it working.

I am trying to user this code in c# 2008 express on Window XP.
I have modified the line below
//Match m = Regex.Match(result, "(?<=

)(.*?)(?=)");
to
Match m = Regex.Match(result, "(?<=overflow:auto\">)(.*?)(?<=)");
This is returning the text but the translation pair is not working as I expected. If I pass in "HELLO MY FRIEND" "en|sp" the result is "HELLO MY FRIEND". If I pass in "HOLA MI AMIGO" "sp|en" I get "HELLO MY FRIEND".
If I passin "HELLO MY FRIEND" "en|da" the result is "Hello my friend". A different font proper case but no translation. Can you throw any lighy on this problem?
Thanks in advance
Bob pointon

Hello my friend

It seems that google has changed its layout of the result page. I choce to use the HtmlAgilityPack, which makes it much easier to handle those changes.

public static string Translate(string input, string languagePair, Encoding encoding)
{
string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);

string result = String.Empty;

using (WebClient webClient = new WebClient())
{
webClient.Encoding = encoding;
result = webClient.DownloadString(url);
}

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(result);
return doc.DocumentNode.SelectSingleNode("//textarea[@name='utrans']").InnerText;
}

Get the HtmlAgilityPack here: http://www.codeplex.com/htmlagilitypack

I hope this will help the translation to keep working for everyone

Have you tried to pass in "en|ar" as the languagePair?
