Master the targeted extraction of data using Beautiful Soup’s find method to precisely capture single elements from complex HTML structures. Streamline your web scraping skills by identifying and retrieving HTML elements using attributes.
Key Insights
- Leverage Beautiful Soup’s
soup.findmethod to efficiently retrieve a single HTML element identified by specific attributes like the key-value pairname="1.1.19". - Understand the structure of HTML tags and attributes, recognizing them as key-value pairs resembling Python dictionaries, to precisely target required data.
- Convert extracted HTML content into usable text by applying the
.get_text()method, demonstrated in the extraction of Shakespearean dialogue: "your oaths are passed, and now subscribe your names."

The other method you'll use most often, besides `soup.find_all`, is `soup.find`—just `.find` one. Often you're looking for a list of elements, but sometimes you're just looking for one specific element.
And again, this is not an incredibly complicated one. We're looking for that one bit that contains our target. Here's how we could do it.
First, a lot of it is just understanding the structure of the HTML. This is an `a` tag. And I know that—if we look back at this `h3` tag, right—that's the little `
` part here.
For these `a` tags, it's `` at the start and `` at the end. But this one also has an extra attribute: `name="1.1.19"`. Actually, I think the one we want is this one—`1.1.19`. Was it? I'm forgetting which line we’re looking for. Yes—`1.1.19`: “that war against your own affections.” No, wait—I keep getting it wrong.
It’s “your oaths are passed, and now subscribe your names.” That sounds like fighting words. I'm kind of pretending I don't know Shakespeare really well.
I do. But it's easier to pretend you're not an elitist. Shakespeare’s great.
Go read some Shakespeare. Anyway, `name="1.1.19"`—this is an attribute, meaning a characteristic. And it looks like—if you're thinking of your Python—it’s like a feature name.
It's an attribute. It's a characteristic. It’s a property.
It’s a key-value pair. We see these everywhere in data. And here we can say, “Okay, this looks like a dictionary.”
Can I say I want the element with the key `name` and the value `1.1.19`? And yes—we can. We can say: find one `a` tag that has this property.
This key-value pair. And here’s how we do that:
We can say `soup.find()`. We’re finding only one, so we use `.find`, not `find_all`. We pass in `"a"`—very similar to how we did it above with `h3` tags.
We say, “No, just find one `a` tag.” We can pass in a second argument—with the attributes. `name="1.1.19"`. We pass it in. We could include multiple attributes to further narrow down the search if needed. But we got this bit of code by carefully examining the page and asking: “What identifying features does this element have in its HTML?” And we found the `name` attribute.
That’s how we’re able to target it and scrape only that specific piece of our vast amount of Shakespearean data. So, I'm going to save that as `line`. It's a line.
And if we look at it—great. Looks like we’ve got it. But it’s not a string.
It prints out as the full HTML of that line. But we want the actual text in the line. And to do that, we call the same `.get_text()` method.
It’s the exact same method—we're just calling it on one element instead of using a list comprehension, as we did earlier. And here we go—the actual string: “Your oaths are passed, and now subscribe your names.”
