QUESTION
Hello fellow R fanatics...
I've been using R to scrape data from a variety of websites for a while now, however this one has me stumped.
I am trying to scrape the data from the following table: http://www.vigimeteo.com/PREV/obs/obs_seul.html?a=07005&b=
However my efforts thus far have failed.
I have tried the following
- Simple wget, which results in the html from the site, and some of the javascript functions used to populate the table, but I haven't been able to really look through it and find the parts that I could use to grab the data using some of R's JS utilities. It might be that my experience with JS is quite poor
- I tried the solution here Reading data from iframe, b/c it looked like the original website had the table in an iframe, but again no luck
A combination of getURL and readHTMLTable
thisURL = http://www.vigimeteo.com/PREV/obs/obs_seul.html?a=07005&b= theURL = getURL(thisURL,.opts = list(ssl.verifypeer = FALSE) ) tables = readHTMLTable(theURL)
This results in an empty table
- Spent about an hour going through every part of the html and javascript code I could find, but with limited success as detailed in 1.
It appears maybe R's Selenium package could have a potential solution, but I haven't yet figured out how to use it here, probably due to unfamiliarity
I feel like I'm just missing an essential part here... perhaps due to my lack of knowledge of JS and XML?
UPDATE:
I've noticed that if I right-click on the table element and use Chrome's "inspect" it generates HTML that has all of the table's values in it and would be very scrape-able... I'm still not sure how to get to this point in R though. Anyone have hints on where to look in the "inspect" screen to try and guide my progress?
...ANSWER
Answered 2019-Mar-10 at 19:24The solution to this was the following.
- Using the source code, identify the source html for the table
- Navigate to the source page, and use Chrome developer tools > Network > XHR
- Refresh the page to find the source of the data
- Scrape from that source
Thanks to @XR SC for his answer here: web scraping using Chrome Dev Tools for providing the basic approach.

Install vigimeteo
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
