In this step, we want to achieve the equivalent of the 'Save As.' function from your favorite web browser. If you have no other alternative and you're willing to accept these limitations, let's proceed to Step 1. And one tweak to the presentation of the web page can break any automated scraping process. The information on the web page does not include data types, lengths, or constraints metadata. Use REST APIs to query for and collect JSON data from web services.

Download and import a CSV file from the web.

Here are two articles that cover different techniques: If you find an official data source to use instead, you might still want to automate its collection and import into SAS. You can save effort and achieve a more reliable result if you can get the official data source. Remember that web sites are run by people, and usually these people are keen to share their information. However, even if the answer is No - it's a simple process to ask for it. Does this include the specific table the user wanted? Maybe - I didn't spend a lot of time looking for it. As one expert pointed out, the CDC shares a ton of data at its dedicated site. In my example page for this post, the source page is hosted by CDC.gov, a government agency whose mandate is to share information with other public and private entities. And with the movement toward open data (especially in government) and data-driven APIs (in social media and commercial sites) - there is probably a way for you to get to that data source directly. But if you find information that looks like data on a web page, then there probably is a real data source behind it. Yes, there are still some cases for it, which is why I'm presenting this article. I'm writing this article at the end of 2017, and at this point in our digital evolution, web scraping seems like a quaint pastime. Step 0: Find the original data source and skip the scrape As an example, I'll present a real question that a SAS user asked about scraping data from the Center for Disease Control (CDC) web site. In the remainder of this article, I'll dive deeper into the details of each step. SAS macro language (%DO %UNTIL processing) or DATA step with CALL EXECUTE to generate multiple iterations of the fetch/parse steps. Use SAS informats to convert text to native data types. Let's map these steps to the SAS programming language: For this stepДATA step, with parsing functions such as FIND, SCAN, and regular expressions via PRXMATCH. This applies to those web sites that serve up lots of information in paginated form, and you want to collect all available pages of data.

If necessary, repeat for subsequent pages.

Process the source content of the page - usually HTML source code - and parse/save the data fields you need.Fetch the contents of the target web page.New SAS users often ask whether there are similar packages available in the SAS language, perhaps not realizing that Base SAS is already well suited to this task - no special bundles necessary. Python and R users have their favorite packages that they use for scraping data from the web. When students/researchers want to apply data science techniques to analyze collect and analyze that data, they often turn to 'data scraping.' What is 'data scraping?' I define it as using a program to fetch the contents of a web page, sift through its contents with data parsing functions, and save its information into data fields with a structure that facilitates analysis. The internet is rich with data, and much of that data seems to exist only on web pages, which - for some crazy reason - are designed for humans to read.
