Online XPath tester that supports higher version of XPath. Currently supports XPath 3.0 and XQuery 3.0 via Saxon-HE 9.7 and XPath 1.0 via .NET XPath engine.
This is a little tools that enables people, like me, to play around with features available in XPath version higher than 1.0. I've been a regular user of freeformatter in the past and then xpathtester, for quick-testing and sharing short XPath demo, mainly around StackOverflow. The tools works very well for testing XPath 1.0, but their support for XPath 2.0 and above seems limited.
Considering the above, and that a great XML processor like Saxon has a free version available, I decided to roll out my own XPath tester, which currently named XPathEval (similar to eval.in that I've been using too).
A version is avaiable at http://xpatheval.apphb.com
Contribution of any form from the community are very welcomed (especially for the GUI/front-end part). This project is created using Visual Studio 2015 community, and all dependencies are restorable from NuGet, so I hope it would be trivial to build the project from anybody's machine given VS2015 is installed.
The .sln includes a Test poject containing serveral unit tests that you can run. However, only a few of the main project codes are covered by the unit test at the moment.
