Hi!
I'd go with an Element selector instead, as it's more flexible IMO.
Your sitemap:
{"_id":"amazon","startUrl":["https://aws.amazon.com/ec2/pricing/on-demand/"],"selectors":[{"id":"gunsnroses","type":"SelectorElement","selector":"div.tab-pane.active tbody tr","parentSelectors":["_root"],"multiple":true,"delay":0},{"id":"Type","type":"SelectorText","selector":"td:nth-of-type(1), th","parentSelectors":["gunsnroses"],"multiple":false,"regex":"","delay":0},{"id":"vCPU","type":"SelectorText","selector":"td:nth-of-type(2)","parentSelectors":["gunsnroses"],"multiple":false,"regex":"","delay":0},{"id":"ECU","type":"SelectorText","selector":"td:nth-of-type(3)","parentSelectors":["gunsnroses"],"multiple":false,"regex":"","delay":0},{"id":"Instance Storage (GB)","type":"SelectorText","selector":"td:nth-of-type(5)","parentSelectors":["gunsnroses"],"multiple":false,"regex":"","delay":0},{"id":"Linux/UNIX Usage","type":"SelectorText","selector":"td:nth-of-type(6)","parentSelectors":["gunsnroses"],"multiple":false,"regex":"","delay":0}]}
P.S. i believe it will work for all the tabs with information you need.
