I was thinking about your question again and came up with this.
Just before I posted I saw that William had taken a similar approach
and offered it in a more compact form.
Anyway , for what it's worth.
I was thinking the dots should only be in the formatting, not in the
input so I stripped them out of the input.

#arr = ["123456", "00/00/00"]
arr = ["12345.67", "$00,000.00"]
#arr = ["1234567890", "(000) 000-0000"]

inp_arr = arr[0].delete(".").split(//)
fmt_arr = arr[1].split(//)
str = ""
fmt_arr.each do |x|
str << inp_arr.shift if x =~ /\d/
str << x if x !~ /\d/
end
p str
