The first update I have today is for toXML. While I find myself using JSON more, I sitll find toXML to be a very useful component. It converts arrays, lists, structs, and queries to XML. Today's update is a simple one. The queryToXML function now lets you specify the columns you want to serialize. This can help keep XML packets a bit slimmer (if only there was such an easy solution for people).
The next update will be in about two hours and will hopefully be a bit more exciting.
You can download toXML here.
