How do I get the match data for all occurrences of a Ruby regular expression in a string?
regex, ruby
Solution
You want
"abc12def34ghijklmno567pqrs".to_enum(:scan, /\d+/).map { Regexp.last_match }
which gives you
[#<MatchData "12">, #<MatchData "34">, #<MatchData "567">]
The "trick" is, as you see, to build an enumerator in order to get each `last_match`.
Problem
I need the `MatchData` for each occurrence of a regular expression in a string. This is different than the scan method suggested in Match All Occurrences of a Regex, since that only gives me an array of strings (I need the full MatchData, to get begin and end information, etc). ``` input = "abc12def34ghijklmno567pqrs" numbers = /\d+/ numbers.match input # #<MatchData "12"> (only the first match) input.scan numbers # ["12", "34", "567"] (all matches, but only the strings) ``` I suspect there is some method that I've overlooked. Suggestions?
