on your second point (use shorter selectors) its has different result when I use shorter selectors rather than full path? 

I would use shorter selectors for several reasons:

• Easy to understand
• Easy to identify
• Easy to test (for instance, if a single class is enough to use it as a selector, checking if it exists on the response of the REST you call, while checking if the full path works is... harder)
• More performant

Hi Mohamad,

João said it all. For the second point, short answer is yes. Having the full selector is only viable when you're scraping a pretty static website, because the full path selector is so so so specific, that if there's some JavaScript that changes the DOM content, you could easily fail to get the desired content.

In your example, follow what João said, and try to get the list of items, then cycle through them to get the details.
For the selector, you can try to use only the class name: '.bl-product-card__description-name', by using the Inspect tools and by doing a search in the DOM (CTRL+F) in the Inspect window, try pasting the previous selector, and you'll see that it picks the name of the products.
