Answer 1

import os
import yaml

# Define the recursive function
def iter( map, match ):
    output = []
    for key, value in map.iteritems():
        if type( value ) == dict:
            output += iter( value, match )
        if key == match:
            output += [ value ]

    return output

f = open( infile, 'r' )
data = yaml.load( f )
f.close()

print iter( data, 'title' )
