I really like this one.. Shows you can use tools like Selenium for out of the box things like scraping API's

15:44 You should try using "contains" . Here is an example: script:contains(model_number)

I'm impressed by how you do it in short lines. I have learnt a lot! Thanks for sharing! At the same time I have a question, I want to do scraping on a web page, but unfortunately the page has a prohibition in the uses and terms section that says that web scraping isn't allowed. I shouldn't do it in such cases. What should I do?

HI, you mention that selenium is the best scape tool, and i saw you last video say that selectolax also is your fav tools, i want to ask what different with them, i just learn about beautiful soup ealry, but not quite good. i look on the youtube , somepeople say use brightdata, but it need cost.

Personally i think using regex on the page's html to extract information from a script tag is a lot easier, and you can do it without having to use selenium. I do it all the time.

@AliceShisori 9 ай бұрын

how would you do it? can you provide an example? I'm struggling with regex but I think the same too. if we know the word patterns and the scraping task is tedious regex would help alot.

@JustSomeAussie1 9 ай бұрын

@@AliceShisori Basically all you need to do is get the content (html) of the page and then do a regex search on the html. If you're looking for some ID on a page that's 12 characters long and contains only a-z, you could do something like: ID_PATTERN = re.compile(r"[(a-z)]{12}"), and then do id = ID_PATTERN.search(html). If it finds a match for the pattern you can do id.group(1) to retrieve the match. If you don't know about capture groups you should look them up, they're very useful

you need to use a browser on modern heavy JS pages that don't render pure html. It's two entirely different problems. The problem is getting the html in the first place, and then yeah... after that you can use just about anything to filter it down to what you want. I also doubt pulling out a list of tags is easier than right click copy (John did it by hand for education purposes, just use xpath or selector or whatever) and a one liner.

Amazing video. I copied the API url for the site and loaded it on a new tab but it just returns non authorised message. Is there a way around that?

@mad1337nes 8 ай бұрын

you need to have session cookies loaded (that will then be passed along). You (usually) can't just rawdog an endpoint. It will work if you have recently visited the site, in that same browser window (if using selenium/playwright)... but you either need to navigate to the site first, or pass a previous session's cookie (if there's a longer expiration).
