            Chrome devtools returns null when element is clearly on page
            Asked 2022-Mar-31 at 12:05

            I try to implement a webscraper.

            I thought the issue was my rust code for the longest time but as the title suggests it seems to be the query selector I am trying to use to locate the element. I am trying to crall this page and extract the href on the twitter follow button.

            When using $$("#follow-button") in chrome devTools I get a null response until the element is inspected then the query returns the correct thing. Could anyone please shed some light on why this element doesn't seem to exist until inspected? I can provide links to rust code if that would be helpful.

            The link is in an iframe. You have to select the Iframes src, and request for it's document, then you can select any of its children.

            Item in list found but when I ask for location by index it says that the item can't be found
            Asked 2022-Feb-05 at 21:57

            I am writing some code to get a list of certain counties in Florida for a database. These counties are listed on a website but are each on individual webpages. To make the collection process less tedious I am writing a webscraper. I have gotten the links to all of the websites with the counties. I have written code that will then inspect the website, find the line that says "COUNTY:" and then I want to get the location so I can actually get the county on the next line. The only problem is when I ask for the location it says it can't be found. I know it is in there because when I ask my code to find it and then return the line (Not the placement) it doesn't return empty. I will give some of the code for reference and an image of the problem.

            county_before_location is a list and you are asking for the index of said list, which is not in r. Instead you would need to ask for r.index(county_before_location[0]).

            nth-child(n) counts all children of the element, regardless of the type of element (tag name). If there are other elements of different type coming before your target element nth-child will fail to find the correct element and may return null.

            However, the selector nth-of-type(n)

            matches elements based on their position among siblings of the same type (tag name)

            and ignores elements of a different type.

            Websites can fail intermittently for many reasons. Perhaps you make too many requests or the server is overloaded or its down for maintenance. Your code should check error codes which will help find out what goes wrong.

            Since you want to keep trying, you could just add that into your code. I've extracted the data gathering into a separate function that only returns when it gets good stuff. This reduces repetition in your code.

            I made a few changes to get it to make a successful HTTP request:

            • Added the Host: field to the HTTP 1.1 request. It's an error not to supply that field.
            • I made it send the proper amount of bytes for GETrqst. It should be strlen(GETrqst), not sizeof(GETrqst).
            • You copy the wrong thing into socket_address.sin_addr in inet_aton(getResult2->ai_addr->sa_data, &socket_address.sin_addr);. You have the correct thing in ((struct sockaddr_in *) getResult2->ai_addr)->sin_addr and need only to copy that.
