Needs work Rated 3 out of 5 stars

On large XML data sets it's unacceptably slow. There should also be a button for evaluating the xpath expression instead of doing it automatically. Again, when dealing with large data sets, it becomes unbearingly slow when it tries to evaluate after every key stroke.
Otherwise a nice add-on.

This review is for a previous version of the add-on (0.4.1).
