Change the fetch detection logic,check "em"

if (line.contains("em")&&line.contains("/"))
{
i = line.indexOf("em");
j = line.indexOf("/", i);
//temp=line.substring(i + 1, j);

// if(!line.substring(i + 1, j).contains("中文")&&!line.substring(i + 1,
j).contains("英文"))
namelist.add(line.substring(i +3, j-1));
//flag2=1;

// continue;
//System.out.println(line.substring(i, j));
}
