Help with Xpathonurl scrape


I am trying to scrape some data from a table on the link below using the following Xpath -


For some reason when I run this, I get a result of N/A which is the data-o_content result where I want to get the "6.6 lbs" back in this case

td class="woocommerce-product-attributes-item__value" data-o_content="N/A">6.6 lbs</td

Any help is much appreciated


It appears the value is being fetched with Javascript and the N/A is a placeholder with the initial HTML. It is possible to fetch using the [Phantom JS Connector]
