If the Web site doesn’t have an API then you will need to scrape text. This isn’t hard but it is tedious. You will need to use rvest to parse HMTL elements. If you want to parse mutliple pages then you will need to use rvest to move to the other pages and possibly fill out forms. If there is a lot of Javascript then you might need to use RSelenium to programmatically manage the web page.
It is an easy to use web data extraction tool that combines best-in-class features with an intuitive visual project design tool, to make your next data mining project a breeze.
Whether faced with routine web scrapping tasks, or highly complex data extraction projects requiring form inputs, proxy server lists, ajax handling and multi-layered multi-table crawls, FMiner is the web scrapping tool for you.
With FMiner, you can quickly master data mining techniques to harvest data from a variety of websites ranging from online product catalogs and real estate classifieds sites to popular search engines and yellow page directories.
Simply select your output file format and record your steps on FMiner as you walk through your data extraction steps on your target web site.
FMiner's powerful visual design tool captures every step and models a process map that interacts with the target site pages to capture the information you've identified.
Using preset selections for data type and your output file, the data elements you've selected are saved in your choice of Excel, CSV or SQL format and parsed to your specifications.
And equally important, if your project requires regular updates, FMiner's integrated scheduling module allows you to define periodic extractions schedules at which point the project will auto-run new or incremental data extracts.
