GCA has moved XML 2006 across the country from the previously annonced Seattle location to Boston. The new dates are December 4-8. I hope nobody bought non-refundable tickets yet.
Todd Ditchendorf has released AquaPath, a free-beer Mac application that can "evaluate XPath 1.0 expressions against any XML document and view the result sequence in a dynamic, intuitive tree representation. AquaPath is based on Apple's Cocoa/Objective-C NSXML and WebKit Frameworks." Mac OS X 10.4 is required.
