1. error using XPath to locate tag

doubt

When getting the anchored tag , The obtained list is found to be empty

seek

Then go to the browser's packet capture tool to see

Find the information you can normally get from the bag raking tool , But you can't get it in the process of crawling
This makes me confused , And then get the network source code in the browser

If the eyes are not sharp or can not be found （ Don't tell me what it is ）, I still haven't found it here
however , I think of an example , When I asked the boss , The boss told me that sometimes the source code of the browser's packet capturing tool may be modified , When you encounter problems, you can analyze the web page source code in the process of crawling, and you will find something .

solve

Get web source ,（Ctrl+F） Search for

So far, it can be found that , There are no spaces in the packet capturing browser , Have to say , These are really dogs .

ps: I have seen this problem before （ Ha ha ha ）, I haven't learned it for a long time and have forgotten a lot , We should look again .
