# 读取 dump 文件内容
with open(dump_file_path, mode='r', encoding="utf8", errors="ignore" ) as flip:
	dump = flip.read()

# 正则匹配	
pattern = r'@interface (.+) :'
r = re.compile(pattern)

for item in sorted(rs):
	print(item)
	if item:
	 # 'a' 追加内容, 'w' 为覆盖写入
		with open(dump_out_file_path, 'a') as flip:
			flip.write(item + '\n')
