Ampersand in title causes parser to fail

See original GitHub issue

The parser will allow an ampersand in the title tag but fails in some instances. The following will cause it to treat all HTML that follows as plain text:

String htmlCode = "<html><head><title>&X</title></head</html>";

System.out.println(page.getTitleText()); prints &x</title></head</html> instead of &x.

The full code to reproduce:

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.StringWebResponse;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HTMLParser;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;

public class HtmlUnitTest {
	public static void main(String[] args) {
		String htmlCode = "<html><head><title>&x</title></head</html>";
		try (WebClient webClient = new WebClient(BrowserVersion.BEST_SUPPORTED)) {
			StringWebResponse response = new StringWebResponse(htmlCode, new URL("http://http://htmlunit.sourceforge.net//test.html"));
			HtmlPage page = HTMLParser.parseHtml(response, webClient.getCurrentWindow());
			System.out.println(page.getTitleText());
			// work with the html page
		} catch (MalformedURLException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

Hi Jeff, thanks for the reminder. Looks like i will not find the time to make the big move and change the parser. Instead of this i will fix it in Neko.

Hope you can be a bit patient about this. I like to switch away from Neko to https://about.validator.nu/htmlparser/. Hope this step will solve this problem also. There is still some work to do and i also have some business task during the next weeks, So please be a bit patient…
