The information crawler of the web page comes in to discuss it.

as shown in the figure three websites, we need to grab the company name, address, and mobile phone number;
the mobile phone number is easy to get, but the accuracy is not very high; for example, there is a string of numbers 1860126157733;
will deduct 18601261577 as the mobile phone number;
company name, the address capture rate is very low;
I don"t know if there are similar friends who can discuss

ps: pictures come from the Internet, because they are open to the public network, and I don"t have a mosaic of information

Then look for keywords: such as company name, mobile phone, name, etc., and find the associated field. Finally, regular assistance is considered.

this is easy, phpspider learn
