Today in this blog post we are going to take a look into: 3 different approaches to Unzip or expand compressed files in PowerShell. All these methods can come handy in different scenarios, like one may be faster and one is supported on all.Net Frameworks, that means it can run on PowerShell v2 as well. ScrapeStorm is an AI-Powered visual web scraper,which can be used to extract data from almost any websites without writing any code. It is powerful and very easy to use. You only need to enter the URLs, it can intelligently identify the content and next page button, no complicated configuration, one-click scraping. ScrapeStorm is a desktop app available for Windows, Mac, and Linux users. Photo by CHUTTERSNAP on Unsplash Hints, Tips, and Conclusion. Terraform state file manipulation is a dangerous art, but often necessary in the early stages of Terraform learning and development. I am writing a program in dot net that will execute scripts and command line programs using the framework 2.0's Process object. I want to be able to access the screen buffers of the process in my program. I've investigated this and it appears that I need to access console stdout and stderr buffers. Jul 29, 2019 Hello!

ExcavatorSharp.WebScraper.x64 ExcavatorSharp is a multi-threaded server for scraping web data. It converts HTML code into a structured array of data. The library allows data scraping from multiple sites in parallel mode, within a single running application. Create scraping tasks and perform data extraction on a schedule. The library is designed for professional extraction and parsing of large volumes of data. Under the hood there are .css-selectors and xpath support, data export into .csv/.xlsx/.sql/.json, online data export, support for proxy servers, dynamic content crawling, interaction with the site via javascript and much more. The library uses .NET Sockets and Chromium Embedded Framework.The library can be used separately as crawler or parser. We support the formats sitemap.xml and robots.txt. We support the gzip / deflate compression.Attention! Only x64 versions are supported for .NET 4.5.2 and 4.6 platforms. AnyCPU build does not support! You will NOT be able to run the library when building AnyCPU. This is caused by the features of CEF. |

There are many reasons you may need a website scraper. One of the biggest reasons I use website scrapers is to prevent me from visiting a site to look for something on a regular basis and losing the time spent on that site. For instance, when COVID-19 first hit, I visited the stats page on the Pennsylvania Department of Health each day. Another instance may be to watch for a sale item during Amazon’s Prime Day.
Getting Started
To get started, we’ll want to create an Azure Function. We can do that a few different ways:
- Use the Azure extension for Visual Studio
- Use the Azure Portal
At this point, use the method that you feel most comfortable with. I tend to use the command line or the Azure extension for Visual Studio Code as they tend to leave the codebase very clean. I’m making this function with C# so I can use some 3rd party libraries.
In my case, I’ve called my
HttpTrigger
function ScrapeSite
.Modifying the Function
Once the function is created, it should look like this:
We’ll bring in the NuGet package for
HtmlAgilityPack
so we can grab the appropriate area of our page. To do this, we’ll use a command line, navigate to our project and run:In my case, I’m going to connect to Walmart and look at several Xbox products. I’ll be querying the buttons on the page to look at the
InnerHtml
of the button and ensure that it does not read “Get in-stock alert”. If it does, that means that the product is out of stock.Our first step is to connect to the URL and read the page content. I’ll do this by creating a sealed class that can be used to help deliver the properties back to the function:
Web Scraping Tools
In this case, I’ll be returning a boolean value as well as the URL that I’m attempting to scrape from. This will allow me to redirect the user to that location when necessary.
While it is not illegal to screen scrape websites, you should make sure that you have the appropriate permission before scraping the site. In addition, if you scrape too often, the site may deem you as a bot and may block your IP address.
Next, I’m going to add a static class called
Scraper
. This will actually handle the majority of the scraping process. The class will take advantage of the HtmlWeb.LoadFromWebAsync()
method in the HtmlAgilityPack
package. The reason for this is that the built-in HttpClient()
lacks the necessary headers to properly call most sites. If we use this library instead, most websites will record us as a bot.After we connect to the URL, we’ll use a selector to grab all buttons and then use a LINQ query to count how many buttons contain the text “Get in-stock alert”. We’ll update the
ProductAvailability
object and return it back.Finally, we’ll update our function to call the
GetProductAvailability
method multiple times:Results
Now, we can run our function from within Visual Studio Code. To do this, hit the
F5
key. This will require that you have the Azure Functions Core Tools installed. If you do not, you’ll be prompted to install it. After it’s installed and you press F5
Metabase. , you’ll be prompted to visit your local URL for your function. If successful, you should see the following results (as of this post) for the above two products:Dotnet Core Install
Conclusion
Dotnet Core Downloads
In this post we created a new Azure Function, built the function using VS Code, and connected to Walmart.com to obtain product information. If you’re interested in reviewing the finished product, be sure to check out the repository below:
