I have one yaml file “content.yml” which has content,

* * *

key: !DBClass  
debug: Y  
Directory : /var/tmp  
name: John  
phone: 487394

As, I am trying to load the file via,

obj= YAML.load(File.open(“content.yml”))

But i dont know that how to acess the individual variable from this  
content.  
for eg, How do i will get the Directory or name or phone ?

There should be some code that defines the DBClass type for YAML (maybe  
you can check with whoever wrote that data?). In the meantime, you can  
do this:

require ‘yaml’

h = YAML.load(DATA)[“key”].instance\_variable\_get(:@value)

p h # {“name”=\>“John”, “Directory”=\>"/var/tmp", “phone”=\>487394,  
“debug”=\>“Y”}

p h[“Directory”] # “/var/tmp”

**END**
