MZ: I obtained this XML code from an internet blog, with permission (see below) It is a very nice simple code, and makes XML parsing and writing easy. The code came from: http://stuffnwotnot.blogspot.com/2009/05/simple-way-to-parse-xml-in-java-2.html I contacted the author to make sure I can use his code in DIARC. As per the the author, Chris, (in one of the comments, in response to my comment): "Hi Michael, This code is completely free so please use it however you like!" The code below is actually an ever-so-slightly expanded version of his XML parsing code, and my own addition of the XML writing code
