|+Simple XPath evaluator which runs against a SAX stream.|
|+Supported XPath construct as of writing are:|
|+ - '/'-axis (child)|
|+ - '//'-axis (self-or-descendant)|
|+ - node name tests|
|+ - predicate test (@<attribute_name> = "<literal>")|
|+A state machine is built which the SAX-nodes are tested against. If a node matches, the state machine progresses.|
|+For self-or-descendant-nodes, the state machine is forked and earch fork (including the parent) is tested against the SAX-nodes. This ensures all nodes are matched. See test/saxpath.js and test/inception.xml for an example.|
