POWER QUERY - Check if a row contains substring from another table

Hi,

 

I wonder, if there is a way, how to look up for values between tables.

For example, there is a table containing (besides other columns) this column

 

String (head)
Holiday in Mexico
Cuba cruise
Best ski resort Canada
Honeymoon Italy
cheap holiday

  

Then, there is another table which contains a list of countries (see below).

Is there a way how to add a column in a table "String" whereas the value in this new column will contain the name of a country if the string contains a country. Otherwise, there will be "null" or just blank()

 

Country (head)
Mexico
Cuba
Canada
Italy

 

So the ourput for this case would be:

 

String (head)Country (head)
Holiday in MexicoHoliday
Cuba cruiseCuba
Best ski resort CanadaCanada
Honeymoon ItalyItaly
cheap holiday 

 

Then, is there a way, how to handle this? (see below)

Check, if there is a value from Countries[Substring] in String[String], if yes, add to String[String] the value from Countries[Country].

In the tables below, in the added column, there will be a value "Canada" and "Italy" becaluse "Canadian ski resorts" contains a substring "Canad"

 

String (head)
Canadian ski resorts
Italian cuisine

 

SubstringCountry
CanadCanada
ItalItaly

 

Thank you in advance for suggestions..

 

Petr
