Hello.
I'm trying to develop a web crawler with VBA which helps me download data from the specific webpage , what i want to do is make in VBA to upload a excel file with product numbers and then to crawl , recently i developed a very easy Crawler which is not a lot specific i have the code , and if someone could change it and make it for specific crawler.
I want from this page : https://www.digikey.com/en/products/detail/3m-tc/3M-1776-12-X-12-6-PK/12144741 to crawl only the Product Attributes.
Below the Photo is the Code.

Sub CountryPopList()
Dim ieObj As InternetExplorer
Dim htmlEle As IHTMLElement
Dim i As Integer
i = 1
Set ieObj = New InternetExplorer
ieObj.Visible = True
ieObj.navigate "https://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_population"
Application.Wait Now + TimeValue("00:00:05")
For Each htmlEle In ieObj.document.getelementbyclassname("wikitable")(0).getelementsbytagename("tr")
With ActiveSheet
.Range("A" & i).Value = htmlEle.Children(0).textContent
.Range("B" & i).Value = htmlEle.Children(1).textContent
.Range("C" & i).Value = htmlEle.Children(2).textContent
.Range("D" & i).Value = htmlEle.Children(3).textContent
.Range("E" & i).Value = htmlEle.Children(4).textContent
End With
i = i + 1
Next htmlEle
End Sub
I've been hunting for some good resources that explore how to build a web crawler that can scale. The best resource by far I have found is a 45 youtube video that digs into the architecture required to build something at scale.
It discusses seed URLs, seeding frontier, fetcher/renderer, storage, Redis for caching, pipelines, bloom filter and other algorithms for content comparison and it even (albeit briefly) discusses building a custom DNS repository for faster DNS resolution.
However, after hours of searching, I've only found these two super elementary implementations of something that sort of resembles a scalable architecture. I'm hoping someone else has found some good resources that I can use to model what I'm looking to build.
Good Evening All!
I'm a huge fan of this sub reddit. Black girl magic on here is amazing and awe inspiring. I want to thank the mods and everyone here for the community and safe space that they've manage to create and foster on an internet that can be very vicious and demeaning to people of color, especially black women. Thank you.
This brings me to why i'm here making this post. I have a dream of creating my own version of black google. The reason for the name is that as black folks we've all experienced searching for things on the internet like mac n cheese recipe, peach cobbler recipe, hair styles, fashion, businesses and or products. However, our experience is somewhat unique for those of us from the diaspora. Locating that type of information in the white dominated internet without the history or roots becomes incredibly difficult. Consequently, most of our searches of the topics previously mentioned end with "for black people" hence my websites name.
So this is very much so a pet project. It's something I intend on completing at some point TBD. However, I'm very much in need of known, trusted, and verified black owned websites, blogs, and brands that create their own content so that I can go and crawl their website and create the references to those sites on my own.
The ask: Send me black owned websites, blogs, and companies that produce content for black people.
PS: If anyone wants to give a beginner python programmer some advice for such a project please do not hesitate. I could use all the help.
Can someone drop an example that would demonstrate the difference between a web scraper and a web crawler? Can a program be both a scraper and a crawler?
I created a program that targets a specific URL, parses and extracts the HTML data, and downloads it to a JSON, however, the program will also continue to scour possibilities of other links to target and continue to crawl until it can no longer find more suitable targets. So I'm confused as to how I would categorize this.
So I recently started freelancing building websites and whatnot. I registered in some websites like freelancer.com but job offers in there receive massive amounts of bids, so I found it really hard to actually land any contract.
Then I started looking in other job boards but I kinda felt burnt out because there's a gazillion of them and I lost a lot of time and energy just looking for jobs.
So I built myself a little job aggregator that crawls job boards in order to find less crowded freelance job offers in an easier way. Now I'm thinking of opening up this tool for other people to use... do you think this is something you would find useful?
Any feedback is greately appreciated, I wouldn't want to invest myself in building an MVP for something that people won't interest :)
Check-it out guys :) Any feedback / testing will be very welcomed.
This is my idea:
I'm planning on creating a web crawler that collects new posts from my favorite blogs and returns the response in a JSON format. I'm familiar with how Django rest frameworks work so I decided to proceed with it. My problem is though how can I call a web crawler from an API with a post request?
I've just written a program that scrapes a website of transcripts of Donald Trump speeches (using requests and bs4), counts all the words used and returns a list by order of occurrence and writes to CSV.
I have been working on Chapter 11 of ATBS so wanted to put web scraping to practice, also trying to ensure I implement logging in my code.
The code is working as I intended, but feel I've probably overcomplicated and done this in a non ideal way so would appreciate any feedback and suggestions on it!
(it does take quite a while to scrape all the pages I have defined, the range in the getlinks() function can be reduced so it visits fewer pages)

I am pretty new to Python, and first time using git, so may have made some rookie errors!

Hello all,
Looking to hire someone to help build a crawler to help find phone numbers, addresses, and business names of companies in the home improvement industry who newly created websites, or social media pages that do some type of work in the home improvement field.
Please bid, and I'll message privately to discuss further.
Thank you,
Hi guys, I made a web crawler to the new Tibia Bazaar feature.
It's usefull if you want to check how much people are selling specific chars, or any information regarding the trade.
In this link you can find a csv file with all the finished auctions, a image explaining each field, and also if you know some python and/or the scrapy lib you can play around with the code.

Any questions just ask
It would be easy for reddit to create a search engine that competes with Google from data it already has.
Would you use a reddit search engine for the web?
Looking for someone experienced to code me a web crawler to crawl and gather the needed information , has to be stable to run 24/7 and mutli threaded.
payment will be made once i check the stability of the crawler and make sure its working.
Please only apply if you've coded one before as i need it asap.
As the title said ive created a web crawler with scrapy that is going to crawl over 20m pages. I want to implement rotating proxies but have never done this before. Any recommendation where I can get reliable proxies? I donβt mind if I have to pay.

I was using a web crawler on Reddit for a program I am building and found this subreddit by random chance. Some of the text seems to be in what I think is binary, but there is also one post with a bunch of what looks like Morse code. I am not a decoder myself but figured you guys might want to check it out. Post what you find out about it here, I want to know what it is!
I am a hobbyist programmer and don't really know much about software architecture or design patterns. The only pattern I am familiar with is the MVC. After having to create more than 2 classes, the code got messy and I am starting to appreciate the value of clean code practices, debugging, testing, handling exceptions properly, etc. I am now looking for a suitable design pattern for my project.
The main components of project are
1- Utility class for connecting to URLS, getting their HTML content, and parsing the content.
2- A runnable class that does the crawling part (polls an unvisited URL from the tasks queue, visits it and collects all hyperlinks in it and adds them to the tasks queue).
3- A GUI class where the user can specify the number of crawler threads, the maximum depth (number of pages to be crawled), the time limit, etc.
What design pattern is best suited for such a project? Should I add more classes?
