Beautifulsoup looping through pages tutorial

Beautifulsoup looping through pages : In this tutorial, we will explain the beautiful soup looping through pages. The loop is the process for continuous free writing. They will involve the idea of free writing and using basics used for free-writing. The click command will clicks multiple links, and clicks on usually have their URLs. They will make it easy for ParseHub to open these pages in new "tabs" and continue clicking on links from the initial webpage. These links will load information on the current page using something that is called an AJAX call. The ParseHub will run into websites using regular methods because clicking on these links does not change the URL. But the HTML structure of the webpage looks completely different. It is not able to refer to the initial page where it clicked on and there is no URL attached to it.

Features are as follows:-

1. Exit condition:-The criteria in which the loop stops and counter reach a certain value.
2. Counter:-It will initialize certain values and is called the start point of the loop.
3. Iterator:-It is called the incrementor as it is used to count by a small amount on loop.

Steps:-

1. Selecting recent free-writing exercise.
2. Then choose a sentence that stands out because of quality and interest.
3. Then the original free-writing example with a line between the two.
4. Read the sentence and free-write again.

ParseHub is not able to find the next element or link to click on and continue the scrape.

You can work with it and get ParseHub looping through pages even if the website is loading information using AJAX.

Looping through AJAX clicks:-

1. We want to extract a text of the category that will be scraping sorting by car makes uses AJAX clicks.
2. Using the command generated for you we click on the "Make" filter on the left-hand side of the website to select it. 
3. Then we rename your Select command to "filter" by clicking on it and then click on the plus button next to "Select & Extract filter".
4. Choose a command from the toolbox. 

5. The click command configuration window pops up then chooses "No" when asked if this is a next page button.

6. Click on the plus button next to "Select page" and choose.
7. by using the Select command in step 4, click on the first to select it.
8. It will get in green while elements will be highlighted in yellow. 
9. Click on a second car make highlighted in green then rename your select command to "make".
10. Then click on the plus button next to "Select page" and click on advanced then choose a toolbox.  

11. in the "List" box, type in "make" if we want to start a new line for every category to scrape in our loop.

12. To scrape the category names we will add a command to our project.

13. In the Extract command's settings we type in "item.name" into the extraction text box. It is to each car make scraped from the "Select make" command.

14. Click on the plus button next to your Begin new entry command then choose a command.

15. Then click on the three dots above the make_filter template and disable "No duplicates".
The enabled ParseHub will avoid scraping pages that it has already visited.
16. Click on the list icon next to "Select make" and delete the Begin new entry command that appears and click on the plus button next to "Select make".
17. Click on advanced, and choose a Conditional command.
