Pathological is a crazy new tool for searching Finder with extreme precision using a simple and powerful query language called XPath. XPath (http://www.w3.org/TR/xpath/) was originally designed as a query language for XML data. Surprisingly, the Finder shares much in common with XML data, and XPath turns out to be a natural way to search for files and folders on your Mac with unprecedented precision. Pathology is the fine-toothed-comb of search tools.
Pathological's XPath engine is powered by Panther (https://github.com/itod/panthro), an open-source implementation of XPath 1.0 in Objective-C that includes the ability to debug the evaluation of an XPath expression step-by-step. Pathological is written entirely in Cocoa/Objective-C so it feels right at home on your Mac.
