Hi,
there seems to be a problem with the selector "element" (a bug de Web scaper ?) but you can achieve to get your extraction with another sitemaps like this one :
{"_id":"test","startUrl":["http://www.bethesda.co.za/Search.aspx?searchKeyword=&Page=0"],"selectors":[{"id":"link","type":"SelectorLink","selector":"h2 a","parentSelectors":["_root","pagination"],"multiple":true,"delay":0},{"id":"title","type":"SelectorText","selector":"h3 span","parentSelectors":["link"],"multiple":false,"regex":"","delay":0},{"id":"manufacturer","type":"SelectorText","selector":"span#ctl00_ctl00_ContentPlaceHolder1_ShopContent_lblProductDetailManufacturer","parentSelectors":["link"],"multiple":false,"regex":"","delay":0},{"id":"code","type":"SelectorText","selector":"span#ctl00_ctl00_ContentPlaceHolder1_ShopContent_lblProductDetailCode","parentSelectors":["link"],"multiple":false,"regex":"","delay":0},{"id":"pagination","type":"SelectorLink","selector":"ul.pagination li:nth-of-type(n+2) a","parentSelectors":["_root","pagination"],"multiple":true,"delay":0},{"id":"price","type":"SelectorText","selector":"span#lblProductDetailPrice","parentSelectors":["link"],"multiple":false,"regex":"","delay":0}]}
