My idea was to scrap from Multiple URLs (common.part/@names)
It started fine, I added 3 URLs to try. Sitemap looks good...
There are several "columns" I want to extract from the website
Several Selectors:
Text, li.column:nth-of-type(1) div div:nth-of-type(1), multiple not checked (also checked, still bad...), [0-9]+.[0-9]+, root_
What I get in CSV:
Scraper checked all the URLs, each one is a separate cell, great
There are two columns for selectors, great
Value - null 
Url: http://example.com
Sitemap:
{id:"sitemap code"}
