Youtube Channel - Infinite Scroll

How to?
#1

Hi there,

First of all, I am a newbie that has run trough all tutorials found and could not find the solution. I have almost no technical background so I am struggling with youtube scrolling

Describe the problem.
I would like to extract the description box of all the videos from a youtube channel. This is working fine however the scrapping ends when no more videos are loaded and this is because I am missing the scrolling. I could manage to scroll only once (in a simpler sitemap) but then it is not scrolling until the end. I would really appreciate some help from the great minds in this forum, I have been trying that for 4 hours and I feel a little bit silly.
Thanks for the support

Url: https://www.youtube.com/user/Styl3m4st3r/videos

Sitemap:
{id:"sitemap code"}

{"_id":"samcro","startUrl":["https://www.youtube.com/user/Styl3m4st3r/videos"],"selectors":[{"id":"videolink","type":"SelectorLink","parentSelectors":["_root"],"selector":"a.ytd-grid-video-renderer","multiple":true,"delay":0},{"id":"showmore","type":"SelectorElementClick","parentSelectors":["videolink"],"selector":"yt-formatted-string.more-button","multiple":false,"delay":"3000","clickElementSelector":"yt-formatted-string.more-button","clickType":"clickOnce","discardInitialElements":"do-not-discard","clickElementUniquenessType":"uniqueText"},{"id":"description","type":"SelectorText","parentSelectors":["videolink"],"selector":"div#description","multiple":false,"regex":"","delay":0}]}

MANY THANKS!!

When selecting an element for the scroll-down selector, choose the one that you would like the scraper to look for when performing the scroll-down.

Secondly, the description can be found within the HTML without having to perform a click, so that can be avoided to simplify the sitemap.

This should do the trick:

{"_id":"samcro","startUrl":["https://www.youtube.com/user/Styl3m4st3r/videos"],"selectors":[{"id":"videolink","type":"SelectorLink","parentSelectors":["channel-scroll"],"selector":"a.ytd-grid-video-renderer","multiple":false,"delay":0},{"id":"description","type":"SelectorText","parentSelectors":["videolink"],"selector":"div#description","multiple":false,"regex":"","delay":0},{"id":"channel-scroll","type":"SelectorElementScroll","parentSelectors":["_root"],"selector":"div[id=\"dismissable\"]","multiple":true,"delay":"1500"}]}
