import java.util.regex.Matcher;
import java.util.regex.Pattern;


public class MatchHostTest {
	
	public static void main(String[] args) {
		String body ="sdfsd<a href=\"/gaoji/preferences.com\">搜索设置</a>fdf&<a href=\"/gaoji/preferences.html\">搜索设置</a>&fd";
		Pattern p = Pattern.compile("<a href=\"(/.*?)\">");
		Matcher m = p.matcher(body);
		String href = "";
		while (m.find()){
			href = m.group(1);
			System.out.println(href);
//			/gaoji/preferences.com
//			/gaoji/preferences.html
		}
	}
}


("<a href=\"(/.*?)\">");
