If you just tack one XML file onto the end of another you will have malformed XML. This is because every properly formed XML document must have a single tag (often called the root or document tag) that wraps the entire document. For example: Is valid, but: Is malformed. ~ Bob Ammerman RAm Systems -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Harold Hallikainen Sent: Saturday, July 05, 2014 11:26 AM To: Pic List Subject: [OT] XML database? 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 i= n 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!
