Here is a question. There is a website in which there are a lot subtitles(US state names). Under the state names, there are a lot city names. Under the city names, there are a lot sub-subtitles. What I am looking for is special service under the city name. If I am looking for the special service under ten different cities, I need to repeat the process for ten times. It is complicated. Do you have a method or use some software to do one time searching to find the special service under all the ten cities ? Thank you in advance.
