Reading from YAML File in Javascript

I am trying to read parameters from a YAML file into Javascript. Is there any good library to do this?

I've tried these libraries: https://github.com/nodeca/js-yaml and http://code.google.com/p/javascript-yaml-parser/

but both libraries only have functions that parse YAML when it is given as a string, instead of parsing straight out of a .yml or .yaml file. Are there any parsers that read YAML from a file and convert them to JS objects?
