Web Scraping Quotes From Good Reads
GoodReads is a very good resource for info about books, authors and interesting quotations.
In this post, I will share a piece of code that will allow you to scrape for quotations from this site. The code is written for python’s Scrapy framework.
To get started with scraping quotes from your favorite author, first of all search for quotes by the author name in the quotes section.
Once you type the author’s name, you can look for css and xpath in the displayed results for finding pointers to scrape data.
Code For Spider
Now that we have data to scrape from, the next step is to create a spider that will scrape data from this page. A spider in scrapy is basically a class that you can use to scrape data from a location. You can find more info on scrapy here.
Basically, we want to loop over each “quoteDetail” section to get the author and quote text.
for sel in response.css('div.quoteDetails '): quote = sel.css('div.quoteText::text').extract() author = sel.css('div.quoteText a::text').extract_first() item = GoodreadsItem() item['author'] = author item['quote'] = quote yield item
Each quote gets extracted as a “GoodreadsItem” object.
Next, to scrape data from the next page, following code can be used:
checkNextPage = response.xpath('//a[@class="next_page"]').extract_first() if(len(checkNextPage)>0): nextPageLink = response.xpath('//a[@class="next_page"]/@href').extract_first() nextPageFullUrl = response.urljoin(nextPageLink) print(nextPageFullUrl)
That’s all the code needed for scraping. It’s quite easy and fun to scrape with Scrapy. Good luck!
