Content of column having several content

Hi,
i started using the tool and everything works fine.
I have now configured the tool to scrap the content of a table.
The problem i am facing is that 1 of my column has several content element.
How can i decide to extract ONLY 1 specific class inside my column ?

Sitemap:
{"header":"Player","name":"Player","extract":true} is the code used for my column inside which i would like to get only one given class.

Thanks for your help !

Hard to diagnose if you do not provide URL. sitemap or HTML code.
