Thanks David for your response!
At this time Tableau does not have the capability to read .xml files. We do have all the data we need in a JasperSoft report through the creation of a custom domain. We have been able to export this file (.xls or .csv) and upload into Tableau. We were just looking for a way to automate this process vs. having to manually replace the file each month.
Do you know if there is a way to create a .csv output file from a gel or XOG script to the local machine?
