I’m a beginner in web scraping and trying to learn how to implement an automated process to collect data from the web submitting search terms.
The specific problem I’m working on is as follows:
Given the stackoverflow webpage https://stackoverflow.com/ I submit a search for the term “web scraping” and want to collect in a list all question links and the content for each question.
Is it possible to scrape these results?
My plan is to create a list of terms:
term <- c(“web scraping”, “crawler”, “web spider”)
submit a research for each term and collect both question title and content of the question.
Of course the process should be repeated for each pages of results.
Unfortunately, being relatively new to web scraping, I'm not sure what to do.
I’ve already downloaded some packages to scrape the web (rvest, RCurl, XML, RCrawler).
Thanks for your help

I am currently working on a job portal kind of project in which we generate links(official government website links) related to jobs through customized search engine. Is there any way to extract the data from these links generated?.
I have tried web scraping but the structure of all the websites are different. So I needed a generic method to extract the data from these websites...?
I'm gathering submissions via a Google Form (to store a list of local businesses) and the responses are stored into a spreadsheet (Google Spreadsheets).
I want to find a way to visualize this data in a searchable list/directory form on my Squarespace website. I have been reaching out on the Squarespace forum however, I had received no response.
I would love if someone can help me get started by providing some advice or methods I can take to go about this since it's a necessary feature for a person project I'm working on.
Thank you so much.
I am curious whether the following automation would be feasible:
search google for a UCP/EAN code number (e.g. 8710103703631)
scrape and parse data (depending on what is available) from the first ranked page concerning Product:
Name
Brand
Model
Picture
Description
Just trying to understand how complicated this might be.
Thank you!
Lookup EAN/UPC codes via API
There are some free web-APIs which (reverse-)lookup barcodes (EAN/UPC) or provide additional information.
For example ean-search.org is an REST API that is queried by the EAN and delivers XML (e.g. provides a link to Amazon for your sample "Philips Sonicare").
Benefit using an API: ready to use data, no scraping needed.
Web-scraping for search-results
For sure you can use search-engines (like google, duckduckgo, etc.) and search for the barcode using the favorite web-scraping library in your desired programming-language:
JSoup (in Java): see this question
Scrapy or BeautifulSoup (in Phyton): see this question
I am trying to automate web scraping for different Physician Names. The process is I am having a list of Physician names in .csv file
The first process is, the names of the Physician should be entered in the search bar of this site.
Then the search button is to be hit.
Then the first link is to be selected.
Then I want to perform web scraping to collect required details of the Physician.
These are the things to be performed.
The same thing is to be applied for every Physician.
Can anyone help me with this process using R?
Google searching 'web scraping with R' brought me this tutorial and this tutorial. Both of these seem simple enough that you should be able to accomplish what you need. Also, heed hrbrmstr's warning, and see if you can acquire the data you need with abusing metacrawler's website.

How can I quickly scrape data from the resulting web pages?
I have tried to scrape with some scraper programs but could not get them to work. Does anyone have a faster way?
Use python requests library. It is pure and fast library. Scraping speed is not only dependent on your code, it also depends on the web site you are scraping.
