I have an array of objects ( nokogiri xml nodes ) and each node is having name
and value
. I want to print them in the format name=value
without iterating in for loop.
if I use arr * "," I'm able to see just the values as below
4900.00,5.00,0.00,-100.00,100.00
6085.00,5.00,1285.00,1185.00,100.00
6015.00,5.00,30.00,-70.00,100.00
5915.00,5.00,0.00,-100.00,100.00
5815.00,5.00,0.00,-100.00,100.00
Is there something that can be done here.
Something like this should work:
array.each do |n|
puts "#{n.name}=#{n.value}"
end
Assuming that your Nokogiri nodes have name
and value
attributes (not child elements), here's one way:
# Convert the array into a new array of strings
namevals = my_array.map{ |node| "#{node['name']}=#{node['value']}" }
# See it with space delimiters
puts namevals.join(' ')
Possibly useful alternative:
# Create a hash mapping unique names to values
namevals = Hash[ my_array.map{ |node| [ node['name'], node['value'] } ]
