regexp or not

[Josselin]

I am not yet a big friend of reegxp.. and I don't actually know if I
should use it or any other function
but I'd like to know the easiest path to do the following :

I get a string person = 'Clara Mint" which is a full name
and I would like to find the object "id" in a collection using this
full name :

people = [ ["id" => "1", "first" => "Jack", "last" => "Johnson"], ["id"
=> "2", "first" => "Ben", "last" => "Kenneth"], ["id" => "3", "first"
=> "Ken", "last" => "Olsen"], ["id" => "4", "first" => "Howard", "last"
=> "Wong"], ["id" => "5", "first" => "Clara", "last" => "Mint"], ["id"
=> "7", "first" => "Che", "last" => "Guevara"]]

any hint to start ?

first, last = person.split(/\s+/)
found_person = people.find { | person |
person["first"] == first and person["last"] = last
}

Also, do yourself a favour and use a Person class - hashes where the
elements have heterogenous meanings make Baby Data Model Design Jesus
cry. And index them in a hash by the first name and last name string pair.

I'd use String#split.

Use regexes to get first and last name, then iterate over the
collection. Untested:

person =3D~ /^(.*) (.*)$/
first =3D $1
last =3D $2
people.each do |peop|
if first =3D=3D peop["first"] and last =3D=3D peop["last"]
print peop["id"]
end
end

I'm wondering whether your data structure is what you want. Right now
you've got an array of arrays of hashes. Are you sure you don't just
want an array of hashes?

first, last = person.split(/\s+/)
found_person = people.find { | person |
person["first"] == first and person["last"] = last
}

Also, do yourself a favour and use a Person class - hashes where the
elements have heterogenous meanings make Baby Data Model Design Jesus
cry. And index them in a hash by the first name and last name string pair.

Fully agree. And take care to use the correct number of equal signs in
all places.

Your are right..
well, the problem is maybe less complicated that it seems..
the structure doesn't exist per se, all data are in a DB, I know that
the full name is a concatenation of existing data in the DB (first +
last) and I need to get the object.
it's an sql problem ( views... ) sorry for raising up a non-ending story ;-))

Working for a collection agency in the SW I found this a very big
problem, especially with Hispanic names where you can have the name
given to us as Juanita Garcia Rodriguez or worse. And of course we may
get it differently from another client. I have to try and split them
properly for Credit Reporting and with hundreds of thousands of names it
has to be done by computer.
