yaml

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

How is it that json serialization is so much faster than yaml serialization in python?

as seen on Stack Overflow - Search for 'Stack Overflow'
I have code that relies heavily on yaml for cross-language serialization and while working on speeding some stuff up I noticed that yaml was insanely slow compared to other serialization methods (e.g., pickle, json).
