Basically, I was searching for the XPATH
So, when I load the page through the Html Agility pack the XPATH mentioned above cannot be found.
It turns out there is a comment before a particular script block I want to parse.
For this site, there are many script blocks and so I would need to narrow it down by the finding this auto-generated comment
<!--Module 328 Buying Options Table--> and the sibling of that node would be the correct script block.
Any idea on how I can search for a particular comment and then just get the adjacent script block?
htmlDoc.DocumentNode.SelectSingleNode("//comment()[contains(., 'Buying Options')]/following-sibling::script")
