Rails: Split text including dollar end euro - ruby-on-rails

Question

I'm using Rails and Nokogiri and I'm trying to parse some website.
This is where I'm stuck:
doc.css('#example > li:nth-child(1)').each do |node|
money = node.xpath('//*ul/li/div/span').text
end
It returns something like:
$100,000£230,000$40,000$9,000€600$800,000
I want to split those items, save them to the database and finally hand them to the view.
So, in the view, I want it to appear like:
(1)$100,000
(2)£230,000
(3)$40,000
(4)$9,000
(5)€600
(6)$800,000
I tried to split those items by this code below.
money = node.xpath('//*ul/li/div/span').text.split(/[$€£]/)
but the result looks like this:
["", "100,000", "230,000", "40,000", "9,000", "600", "800,000"]
And I don't know which item is in Dollar, Euro, or Pond.
Is there any good way to solve this problem?

Answer 1

you're almost there,
just use the positive lookahead :)
irb(main):005:0> "$100,000£230,000$40,000$9,000€600$800,000".split(/(?=[$£€])/)
=> ["$100,000", "£230,000", "$40,000", "$9,000", "€600", "$800,000"]

Answer 2

It needs a regular expression. This works:
"$100,000£230,000$40,000$9,000$600$800,000".scan(/([^\d][0-9,]+)/)
=> [["$100,000"],
["£230,000"],
["$40,000"],
["$9,000"],
["$600"],
["$800,000"]]
The regex contains these parts:
[^\d]: A character class matching a single non-digit. This will match the currency symbol.
`[0-9,]+': Another character class, this time repeating (the '+'). It matches the numeric part (0-9) plus the thousand's separator.
