[Freeswitch-users] Designing a schema for CDRs

Hi. I have recently been trying to process CDR from mod_xml_cdr and store it in a db I first parsed and wrote all the information in a file, then designed a database based on the fields that appeared in the file. But it seems that FS adds/removes fields sometimes. This causes my query to fail as my program tries to insert columns that do not exist. Is there a way to figure out all the possible fields that might appear in the xml sent by mod_xml_cdr?
