How to use Selenium for web scraping in VBA?
I'm trying to scrape the title and content of articles on a website.
I'm using the latest version of Selenium (3.0.1) in VBThis is what I've come up with so far:
Sub Main(). Dim driver As New ChromeDriver. driver.Start "chrome" driver.get "" With driver. .FindElementByName("q").Click
.SendKeys "selenium" .FindElementByName("input").SendKeys "Ariel"
.SendKeys "Selenium is cool" End With. End Sub. I know the code doesn't look great, but it's my first time working with Selenium and I'm not sure if this is the best way to approach this problem. Any suggestions? This is my first time working with Selenium. The above code should work. If not, try clicking on the right side of the nav menu to refresh the page and then go through the process again.
Is Selenium good for web scraping?
I've been searching for the answer to this question for a long time, and can't seem to find answer I fully accept. To put it plainly: Does Selenium serve any actual use in web scraping (using python) other than as a user-friendly API? Or is it just a way to make UI tests for web applications? (It also seems that Selenium has some kind of relationship with web scraping--if that's what you mean by using Selenium's UI). Are there better/more efficient solutions to web scraping (that don't involve JavaScript)? Can web scrapers be made more efficient by only downloading pages if they have been accessed on-site? Can web scrapers be made even more efficient by caching downloaded data in local RAM (using SQLite or another method)? Can web scrapers be made even more efficient by saving data to external disk without reloading pages after every save? Why are these things missing from web scraping libraries? I'm sure there are a lot of other ways to improve efficiencies in web scraping, but I haven't seen anything that seems to address them in a comprehensive manner. When I read your question I was thinking "surely the answer will be "no", because of selenium". But then I looked at you background, and realized I could be wrong.
That said, I see two possibilities for "yes": it was mentioned in the comments already. Use Firefox :) your example was only a very short description of a very complex thing. Seleniums "scrape" functionality gives you what you have when you call your own selenium-wrapper, with the exception of the javascript. It's really only a wrapper around all things that could give you trouble, like java code or dynamic content(javascript). So if your problem boils down to "my page doesn't do what it should", and nothing else happens on the page that would cause the rest of the page to not behave as expected, you're good, you're covered.
But even then, there's probably more efficiency that you would get out of building your own.
Can VBA do web scraping?
- Ask.
Com
Hello. I'm working on a project with some friends who are in other time zones. We need to scrape as much data from an ASK site as we can, about each category and keyword. We already have the code for this part. I will be providing you with a website URL. This task requires you to write a script that:
Extracts the title and url of the link of the products on each webpage. Extracts the description of the. Develop an automated Excel based VBA script to crawl through a list of website links from an Excel sheet, to download the page content from the web page and save it to an Excel sheet. The VBA script needs to: 1) extract the links from an Excel sheet. 2) start the download of the content of the pages for each . We would like to have someone create a vba web scraper that will search for certain keywords over different websites and download them into an excel spreadsheet (it's a lot of data). We would like to have it set up so the first site you go to it automatically scrapes all of the keywords and the next site you.
I need a web scraper/webcrawler in vba or php preferably. This is for my personal project, not for commercial purposes.
Requirements are listed below: I will provide URLs for crawling (they will change but each crawl will be a different URL). For each URL that is provided, I want to get a summary. I need some help with web scraping. The job is simple - collect data from a couple of sites (some very common information, and some more niche), store it in a database, and then display it to me in a nice GUI/spreadsheet using a simple GUI (no programming required).
We would like to have someone create a vba web scraper that will search for certain keywords over different websites and download them into an excel spreadsheet (it's a lot of data). We have a client who is interested in having their customers create their own profiles.
