YAML - Time to give?

Ruby
1

Guys-
I am trying to create an YAML file like the following:
3
— Begin
ga:
name: Georgia
capital: savanah
population: 1 mil
cities:
city:
name: Atlanta
zip: 30328
city:
name: Savanah
zip: 30304
tx:
name: Texas
capital: Dallas
population: 2 mil
cities:
city:
name: Fortworth
zip: 22222
city:
name: Dallas
zip: 12345
#—End

I keep getting “parse” error while loading it to yaml. Even if I manage
to load with “-”, I could never fetch the City and zip details. Can
anyone help me with this nested yaml file? thanks

One problem is that you’ve just redefined the “city” key for this
hash. So you’ll end up with Savannah but no Atlanta.

When I cut-and-pasted your text and did a YAML.load on it, it worked
fine (other than the logic error with the “city” key). Do you have a
tab character in the file somewhere, instead of leading spaces?

Try this and see if it prints 30328:

str = <<EOM
ga:
name: Georgia
capital: Savannah
population: 1 mil
cities:
Atlanta:
zip: 30328
Savannah:
zip: 30304
EOM
require ‘yaml’
info = YAML.load(str)
p info[“ga”][“cities”][“Atlanta”][“zip”]

Thanks dave. I believe I had tab spaces, which caused load error -
correct me if I am wrong. You suggestion works. However, I wrote a
program that outputs the yaml file with hardcoded values. Then I edited
the output files to match my needs - works beautifully.

Thanks
