import java.util.regex.Matcher;import java.util.regex.Pattern;  public class GetTag {public static void main(String[] args){    String str = "abc
     
      def
     deftfh
     
      a
     ";     Pattern p=Pattern.compile("
     
      (\\w+)
     ");    Matcher m=p.matcher(str);    while(m.find()){        System.out.println(m.group(1));            }      }}
