Parsing repeated matches from a ruby string?

Question

Maybe I'm just pretty tired, but I don't see an obvious way to parse out the numbers from a string like this:

some text here, and then 725.010, 725.045, 725.340 and 725.370; and more text

One thing that occurred to me: split this by spaces into an array. Then apply a regex test with a group to each element in the array.

Is there a cleaner, simpler way to do this?

Thanks for the answers, everyone. I had forgotten about String#scan. These are statute numbers, by the way. — Dogweather

your_string.scan(/\d\d\d\.\d\d\d/)

will output array of matches.

result = subject.scan(/\d+(?:\.\d+)?/)

This will find integers or decimals in a string and put them (still as strings, though) into the array result.

To get them as floats, just do result = subject.scan(/\d+(?:\.\d+)?/).map(&:to_f).
