You can find the Beautiful Soup documentation here. You'll find a lot more tools for searching and validating HTML documents.Pune, Oct.
This is only a simple Beautiful Soup example, and gives you an idea of what you can do with HTML and XML parsing in Python.

If Yahoo changed the way they format their HTML, this could stop working. If you plan to use code like this in an automated way it would be best to wrap it in a try/catch block and validate the output. This works, but you should be careful if this is code you plan to frequently reuse. We need to get one level higher and then get the text from all of the child nodes of this node's parent. That's what this code does: Another thing to note is that we have to wrap the attributes in a dictionary because class is one of Python's reserved words. From the table above it would return this: If we had just gotten td's with the class yfnc_h we would have gotten seven elements per table entry. We chose this because it's a unique element in every table entry. This uses BeautifulSoup's findAll function to get all of the HTML elements with a td tag, a class of yfnc_h and a nowrap of nowrap.
> soup.findAll(text='AAPL130328C00350000').ġ10.00AAPL130328C003500001.25 0.000.901.051010īingo. It's still a little messy, but you can see all of the data that we need is there. If you ignore all the stuff in brackets, you can see that this is just the data from one row.įor y in soup.findAll('td', attrs=) We don't see all the information from the table. Let's try the next level higher. This result isn’t very useful yet. It’s just a unicode string (that's what the 'u' means) of what we searched for. However BeautifulSoup returns things in a tree format so we can find the context in which this text occurs by asking for it's parent node like so: Let's search the soup variable for this particular option (you may have to substitute a different symbol, just get one from the webpage): We can see that the options have pretty unique looking names in the "symbol" column something like AAPL130328C00350000. The symbols might be slightly different by the time you read this but we can solve the problem by using BeautifulSoup to search the document for this unique string. Now we can start trying to extract information from the page source (HTML). The following code will load the page into BeautifulSoup: If you haven't installed BeautifulSoup already, you can get it here.

BeautifulSoup is an external module so you'll have to install it. It will be Python's job to simplify and extract the useful data using the BeautifulSoup module. If you go to the page we opened with Python and use your browser's "get source" command you'll see that it's a large, complicated HTML file. This code retrieves the Yahoo Finance HTML and returns a file-like object.
