在一个哈希中将红宝石哈希中的键值分组并打印特定值

Question

This is my hash:

{"Specialty"=>"Other (note in description);Medical;Dental;Vision", "Value"=>"https://www.example.com/ca"}
{"Value"=>"P.O. BOX 60007 LOS ANGELES, CA 90060"}
{"Specialty"=>"Pharmacy;Medical", "Value"=>"800-824-0898"}
{"Specialty"=>"Urgent Care;Medical", "Value"=>"800-700-9186"}
{"Specialty"=>"Urgent Care;Emergency Care;Medical;Chiropractor;Acupuncture", "Value"=>"800-677-6669"}
{"Specialty"=>"Pharmacy;Medical", "Value"=>"https://www.example.com"}
{"Specialty"=>"Claims", "Value"=>"https://www.example.com/consumer/claims/claimsoverview"}
{"Specialty"=>"Urgent Care;Emergency Care;Medical;Chiropractor;Acupuncture", "Value"=>"https://example/example/apps/services/www/ABCBS/mobilewebapp/default/index.html#/providers/search"}
{""Specialty"=>"Claims;Customer Service;Medical", "Value"=>"800-888-8288"}

You can see from this that the key value has differed values in each hash table, and I would like to print only one specific value, that is PO BOX 60007 LOS ANGELES, CA 90060

I tried printing the values of the hash by hash["value"] and it prints all the contents of the values. I tried loading them into an array[] by using to_s function to print the value I want, but one array is loaded with all these values or I may be loading the array wrong.

array = []
array = medical.split("\n")
text = array.to_s
text1 = array.index{|s| s.include?("P.O.")}
puts text1

Can someone help me with how do I print that specific hash value inspite of various values existing in the key named value

Answer 1

If that's the pattern of the hash specifically, uniqueness I can figure out is that all hashes have multiple keys except the one you are looking for..considering it as an array of hashes

hashes.each{ |hash| break hash['Value'] if hash.keys == ['Value'] }

UPDATE

From the comments, instead of printing the hashes individually you can check and print the required value directly..

results1.map{ |result1| (value = result1['Value']).include?('P.O. BOX') ? value : nil }.compact

It will return array of strings having substring PO BOX

Answer 2

Assuming your have an array of hashes and you want to search for 'PO' strings then you can do this:

arr.select { |hash| hash["Value"][/P\.O\./] }.flat_map(&:values)
#=> ["P.O. BOX 60007 LOS ANGELES, CA 90060"]

Answer 3

array_hashes = [
    {"Specialty"=>"Other (note in description);Medical;Dental;Vision", "Value"=>"https://www.example.com/ca"},
    {"Value"=>"P.O. BOX 60007 LOS ANGELES, CA 90060"},
    {"Specialty"=>"Pharmacy;Medical", "Value"=>"800-824-0898"},
    {"Specialty"=>"Urgent Care;Medical", "Value"=>"800-700-9186"},
    {"Specialty"=>"Urgent Care;Emergency Care;Medical;Chiropractor;Acupuncture", "Value"=>"800-677-6669"},
    {"Specialty"=>"Pharmacy;Medical", "Value"=>"https://www.example.com"},
    {"Specialty"=>"Claims", "Value"=>"https://www.example.com/consumer/claims/claimsoverview"},
    {"Specialty"=>"Urgent Care;Emergency Care;Medical;Chiropractor;Acupuncture", "Value"=>"https://example/example/apps/services/www/ABCBS/mobilewebapp/default/index.html#/providers/search"},
    {"Specialty"=>"Claims;Customer Service;Medical", "Value" => "800-888-8288"}] 

> array_hashes.select{|h| h["Value"].include?("P.O.")}.flat_map(&:values).first
#=> "P.O. BOX 60007 LOS ANGELES, CA 90060"
