webbotparseR allows to parse search engine results that where scraped with the WebBot browser extension. A similar python library is also available.

Installation

You can install the development version of webbotparseR like so:

remotes::install_github("schochastics/webbotparseR")

The package contains an example html from a google search on climate change.

library(webbotparseR)
ex_file <- system.file("www.google.com_climatechange_text_2023-03-16_08_16_11.html", package = "webbotparseR")

Such search results can be parsed via the function parse_search_results(). The parameter engine is used to specify the search engine and the search type.

output <- parse_search_results(path = ex_file, engine = "google text")
output

The function base64_to_img() can be used to decode the image and save it in an appropriate format.
