Plug in that generates XML file

Hello,

I have a plug in that takes a CSV file, generates an XML file saves it to a subfolder in said plugin directory. Then the XML is used to populate a page with a table and used to sort the region and postal codes of the the data.

We are using XML instead of DB because it seems to run faster this way.

Works locally, works on a staging environment, but not on the mirrored production environment (Which I guess means its not so mirrored).

I don’t have access to config etc on these environments. The host has indicated that they have changed the permissions on the sub folder to be as those in staging, but the Page is still not reading the XML file to populate the table…at least that is my assumption.

Has anyone done something similar and run into this type of situation?

Thanks
