Cells and caption ( | or ||, ! or !!, and |+) hold content, so separate any attributes from its content with a single pipe ( |).Attributes should be separated from each other with a single space. All of the markup, except for the table end, optionally accepts one or more HTML attributes, which must be placed on the same line as the mark.Any blank spaces placed at the beginning of a line are ignored. All of the markup listed above must be placed on a new line, except for the double || and !! for adding consecutive cells to a line.Consecutive table data cells may be added on same line separated by double marks ( ||) or start on new lines, each with its own single mark ( |). Consecutive table header cells may be added on same line separated by double marks ( !!) or start on new lines, each with its own single mark ( !). Table row, optional on first row-wiki engine assumes the first row Table caption, optional only between table start and table row 6.3 Common attributes for columns, column groups and row groups.4.7 With HTML attributes and CSS styles.There might be some other beautifulsoup APIs I don't know, but you can drop this in your code and it should work. Table = table_heading.find_parents('table') And you can grab it with something like table_heading = soup.find('th', text='Racial composition') # this gives you the `th` You look at it and see it's got the Racial composition in the heading. This makes it harder to scrape.Īt this point, I would say you're left with just looking at the browser page and thinking about how you would naturally identify the table (non-programatically). Unfortunately, the body of Wikipedia articles seem to be wrapped in just one big element, without semantically separating the sections. With the plan being that you add the parent in the selector. Then, you need to go further up the DOM tree, and check its parents if they have any uniquely identifiers. Had it had any thead, or a caption of some sort, you could have tried with that, but again, it's not the case. The box can be surrounded by lines (a 'border') to show the edges of the box. There's quite some tables on that page so how do I correctly point towards that table?įirst, you you can hook up to some unique identifier, such as an id of the element, but there's none available in your case. A wikitable is a box of rows and columns used to show data, on a page. This is why your program doesn't find any matching table element. If you check the table on the page, you'll see that its classes are wikitable collapsible collapsed mw-collapsible mw-made-collapsible, and there's no sortable class in there. If you check the value of table, you'll see that it is None, and that's why calling find_all on it fails. I'm guessing it can't locate the right table? Soup = BeautifulSoup(website_url,'html.parser') This will return all the table tags in a list, then it's a matter of finding the index posiotn of the table you want. find_all(), and even then you'd need to iterate through those to get the table you want.Īs someone stated, you could also use pandas'. If there are multiple elements, you need to use. Unless the table you are trying to grab has a specific, and unique attribute to identify it, using. find() will only return the first element it finds. Then, use the pipe symbol for information/values listed in the body of the table. you would need to use regex to find classes that CONTAIN that substring, as that would work. To make a sortable table (so you can sort contents by date, number, or alphabetically), assign your table the class wikitable sortable in the first line of code and use exclamation marks for the table headings instead of the pipe symbol. The issue is it will not return a table with class="wikitable sortable collapsible" because it's not explicitly in the html. I'm guessing it can't locate the right table? There's quite some tables on that page so how do I correctly point towards that table? I suppose this is code from the Wikipedia page that we'd need to get: > 5 headers = ĪttributeError: 'NoneType' object has no attribute 'find_all' Here's the code I tried first: website_url = requests.get('').text In the page source, the table seems to start at row 1470. I've been trying to scrape a table on Wikipedia using Beautifulsoup, but encountered some problems.
