I have a bunch of pic32 systems posting xml to a server. I could have the server parse the xml and save the data in mysql. Another possibility would be to just append new xml to the old in a text file, then access the data in that file to generate reports. I like the simplicity of just saving the xml. I'd like to hear comments on this and suggested xml database engines to search the data. This is running on a centos system. Thanks!
