Hi i have a yaml file like so

---
data:
  - date: "2004-06-11"
    description: First description

  - date: "2008-01-12"
    description: Another descripion

How can i do a "ypath" query similar to xpath for xml ? Something like "get the description where the date is 2004-06-11"

YAML.parse_file('myfile.yml').select('/data/*/date == 2004-06-11')

How do you do it, and if that's possible how can i similarly edit the description by 'ypath' ?

Thanks
