Agenty scraping agents are easy and powerful tool for website scraping. Using the scraping agent, you can create your web scraper online and run it on Agenty web scraping software on cloud (or via our API) to scrape the data from thousands of websites in minutes
To create a custom scraping agent- First, you’d need to install our Chrome extension from Chrome store.
Once the extension is installed, go to the web page you want to scrape the data from. Then, launch the extension by clicking on the robot icon on top right side. It will display a panel in right side as in the this screenshot.
Text Scraping
Once the extension panel is up and visible -
- Click on the
Newbutton to add a field and give a name to your field as I did and named itProductName. - Then click on the
(asterisk)button to enable the point-and-click feature to easily generate automatic CSS selectors when you click on the HTML element you want to scrape. For example, I want to scrape the name of products in this field. So, I clicked on the product name element on HTML, and the extension automatically generated the selector for that element and highlighted the other matching
products with same selector on this page.
Sometime you may see other matching items might be selected, due to same CSS class or selector — So you can click on the yellow highlighted items to reject them or can also write your selector manually by learning from here.
Web Scraper Api
The extension will highlight the matching result, and will also show you the result preview under the field. Once you are satisfied with the result and the number of records looks per your expectation, click on the Accept button to
save that field in your scraping agent configuration.
Now, follow the same process, to add as many fields as you want for text, attribute or html items to scrape anything from a html pages.
Hyperlinks Scraping
To scrape URL hyperlinks from websites, we need to extract the href attribute value, so after generating the CSS selector of hyperlink a element —
- Select the the ATTR option in extract type
- Enter href in the name of attribute box, to tell Agenty that you want to extract the value of href in output instead the plain text or HTML.
Images Scraping
To scrape images from websites, we need to extract the src attribute value, so after generating the CSS selector of image element —
- Select the the ATTR option in extract type
- Enter src in the attribute text box, to tell Agenty that you want to extract the value of src in output for images scraping.
HTML Scraping
If you are looking to scrape the full HTML tag instead the plain text or some attributes from the element.
- Write your selector
- Select the extract type as : HTML
Attribute Scraping
Advanced Web Search
The ATTR (attribute) option in scraping agent is very powerful feature to extract any attribute from a HTML element. For example —
- We used src attribute for images scraping
- And href attribute for URL scraping
- Similarly, we can extract HTML data-* attributes, class, id or any other attribute given in HTML to add in our web scraping data
As I scraped ALT attribute in this example HTML page, and named the field : ImageALT
Preview Result
You may preview or download the scraped data in JSON, CSV or TSV formats on extension itself -
- Click on the Options drop-down button
- Then Preview result option will open a dialog box with all the fields result combined in an JSON array of objects.
Save the Agent
Once you are done with setting up all the fields in your agent, click on the Save button to save your web
scraper in your Agenty account.
if you are using the extension first time — The extension will ask you to sign-in on your account before you can save the agent. So, create your free Agenty account or enter the credentials to login.
Remember — The Chrome extension is used to setup the fields of scraper initially, for a particular website scraping. After that, the agent should be stored in your Agenty account for advance features like scheduling, batch
crawling, connecting multiple
agents, plugins etc.
Once the agent is saved in your account, it will looks like this:
Now, no need to go back to Chrome extension ever, you may simply click on Start button to start the scraping on-demand or can use our API to run it from programming language like Python, Perl, Ruby, Java, PHP or C#…etc.
Crawl more pages
The scraping agent can be used to crawl any number of similar structure web-pages. All you need to do is enter the URLs in input for batch crawling or you may use the Lists feature to upload the file and select that in your agent input.
- Go to input tab
- Select input type : MANUAL
- Enter the URLs and Save the input configuration
- Now, just start the agent to crawl all web-pages.
Web scraping tools automatically extract data, which is typically only accessible by visiting a website in a browser. By doing this autonomously, web scrapers can assist with business data analysis, statistical researches, etc.
Web Scrapers in 2020
Today information is more accessible to people than ever before. Still, the colossal amount of it creates a problem of identifying only interesting, truthful, and, most importantly, relevant pieces of information.
As our eyes and brains can’t handle all the incoming information, web scraping has been developed as a useful method of gathering data programmatically from the internet, saving people’s time on the manual web search. Web scraping is the abstract term that defines the extraction of data from different websites and storing this information locally.
Think of a type of data, and you can probably collect it by scraping the web. From the number of candidates for an open position in your area to the number of times your company was mentioned online – various types of data can be sought out and saved by writing a short script.
The Big Debate Over Web Scraping
In late 2019, the US Court of Appeals denied LinkedIn’s request to prevent HiQ, an analytics company, from scraping its data.
The decision was a historic moment in the data privacy and data regulation era. It showed that any data that is publicly available and not copyrighted is a fair game for web crawlers.
The decision does not, however, grant HiQ or other web crawlers the freedom to use data obtained by scraping for unlimited commercial purposes, nor it grants web crawlers the freedom to get data from sites that require authentication.
But since publicly available sites can not require a user to agree to any terms of service before accessing the data, users are free to use web crawlers to collect data from the site.
How does a web scraper work
Here is an example of implementing a web scraper into your analytics to extract data from Google Chrome to Excel spreadsheets.
Another example demonstrates web scraping from web sites such as Yelp and Google Maps using XLS methods.
