Correct XML Fatal Error
Correct XML Fatal Error

This morning, the data compiler stopped working because the FAA posted TFRs which have detailed XML files that return a 404 error. Adding the httr package allows me to confirm the XML file exists (HTTP status 200) before trying to fetch data from the XML file, avoiding fatal errors that stop data processing in its tracks.
