Lxml - Processing XML and HTML with Python. Lxml: an underappreciated web scraping library. When people think about web scraping in Python, they usually think BeautifulSoup . That’s okay, but I would encourage you to also consider lxml . First, people think BeautifulSoup is better at parsing broken HTML. Lxml parses broken HTML quite nicely. I haven’t done any thorough testing, but at least the BeautifulSoup broken HTML example is parsed better by lxml (which knows that <td> elements should go inside <table> elements). Second, people feel lxml is harder to install. Web scraping with Python for fun and profit. Web is everywhere, we know.
It is also used more and more to present information to a wide audience. Sadly, it is commonly the only way data is presented... That said, we need to get that info; the process of extracting information from web pages is knows as web scraping, and note that's is a very fragile process: every time the webpage changes, it's likely you'll have to modify the code that parses it. Beautiful Soup Documentation — Beautiful Soup v4.0.0 documentation.
Beautiful Soup is a Python library for pulling data out of HTML and XML files.
It works with your favorite parser to provide idiomatic ways of navigating, searching, and modifying the parse tree. It commonly saves programmers hours or days of work. These instructions illustrate all major features of Beautiful Soup 4, with examples. I show you what the library is good for, how it works, how to use it, how to make it do what you want, and what to do when it violates your expectations. Query Language. What is YQL?
The Yahoo Query Language is an expressive SQL-like language that lets you query, filter, and join data across Web services. With YQL, apps run faster with fewer lines of code and a smaller network footprint. Yahoo and other websites across the Internet make much of their structured data available to developers, primarily through Web services. To access and query these services, developers traditionally endure the pain of locating the right URLs and documentation to access and query each Web service. With YQL, developers can access and shape data across the Internet through one simple language, eliminating the need to learn how to call different APIs. How Do I Get Started? 110% Easier Web Scraping With The Yahoo Query Language Library. I've been examining and evaluating web scraping frameworks for Python over the last month and have found a few really good ones.
The issue that I've been having though is they require too much time and effort for most people who simply want to perform quick and dirty scraping operations for small personal projects. Today while surfing dzone I found a library that I think is way better for the needs of the majority of script writers; Yahoo Query Language. "The Yahoo! Query Language is an expressive SQL-like language that lets you query, filter, and join data across Web services.
With YQL, apps run faster with fewer lines of code and a smaller network footprint. " In addition to being able to use a SQL-esque language for querying pages/services you can also use XPath selectors in the query statements to make it even easier to grab the data that you want. Beautiful Soup: We called him Tortoise because he taught us. You didn't write that awful page. You're just trying to get some data out of it. Beautiful Soup is here to help. Since 2004, it's been saving programmers hours or days of work on quick-turnaround screen scraping projects. If you have questions, send them to the discussion group. If you find a bug, file it.

In searching for some information on web-scrapers, I found a great presentation given at Pycon in 2010 by Asheesh Laroia. I thought this might be a valuable resource for R users who are looking for ways to gather data from user-unfriendly websites.

Webscraping with Python and BeautifulSoup. Recently my life has been a hype; partly due to my upcoming Python addiction. There’s simply no way around it; so I should better confess it in public.
I’m in love with Python. It’s not only mature, businessproof and performant, but also benefits from sleekness, great performance and is just so much fun to write. It’s as if I were in Star Trek and only had to tell the computer what I wanted; never minding how the job actually it is done. Even my favourite comic artist(besides Scott Adams, of course..) took up on it; so my feelings have to be honest. In this short tutorial, I’m going to show you how to scrape a website with the 3rd party html-parsing module BeautifulSoup in a practical example.
First of, place BeautifulSoup.py in your modules directory. What we will do: go to dict.ccenter a search word into the webformsubmit the formread the resultparse the html codesave all translationsprint them. Web scraping with python. Build a basic Web scraper in Python. There are times when your programs need to access the Web without worrying about the details of the mark-up. In this example we write a HTML scraper using the Python parsing library BeautifulSoup. The Web holds a truly awe inspiring amount of information, which we're all usually happy enough to access through our Web browser. There are times, however, where your programs need to access it, and you don't want to worry about the details of the HTML mark-up. There are thousands of HTML (or SGML, or XML) parsing libraries for hundreds of languages out there, but for this example we use a Python library called BeautifulSoup which takes care of almost all of the work for you.
The BeautifulSoup library is an extremely helpful tool to have at your disposal, since it not only gives you functions to search and modify your parse tree, but it also handles the broken and malformed HTML you're likely to encounter on an average Web page.
