I have been trying to retrieve all the tables of this website (https://www.spensiones.cl/apps/carteras/genera_xsl.php?fecpro=201911&listado=8&tipofondo=B) without having to manually datascrape each table . Basically i want to be able to detect all the tables that exist and then transform these into csvs. So far (refer to the image below) i have made a for each child tht does detect how many tables there are on the website and then i created a variable that will have the idx number of each table so that it can iterate. The problem is that in Assign when i put idxIndex to item.Selector.GetTag(item.Selector.GetTagCount-1).GetAttributeValue(“idx”).ToString (which should work I believe) it tells me that Error: Object reference not set to an instance of an object.I need this because later on in the Extract Structured Data ‘TABLE’ in selector i want to put . This would help me iterate through the tables.
