I am trying to get the values for tracking of an E-commerce website. The values are stored in a form with this selector the element is just in the td. :

form > table > tbody > tr:nth-child(5) > td:nth-child(3) > b

As part of the selector, this is normal. But The tr:nth-child(5) is growing each time a new product is added the child grows so if have 2 products this will be tr:nth-child(6) and so on. I try to capture the count of element with document.querySelectorAll(selector).length but no luck. is there another way to get the value if the node children are increasing?

I am kind of new to scrapping with javascript.

Thanks. George

reach till tbody from queryselectorall and then use siblings to determine what data you want , further you can also use queryselectorall. – Vishal Sharma Nov 23 '17 at 13:41
Thank I used a different strategy I took the ".childNodes" to get the length and from then I start to work. – GeorgeMeSa Nov 27 '17 at 09:06
