Perhap:

the moon'

a = string.scan(/\b\w+/)
["my", "uncle", "jumped", "over", "the", "moon"]

Subject: splitting a string into words using multiple possible
separators

Hi,



I'm using ruby 1.8.5



i have an input string whose 'words' are separated by whitespace and/or
commas and/or semicolons



I want to remove the separators (,;\s) and place each 'word' into an
array



e.g.,



this string => 'my uncle, jumped over;

the moon'



would be converted into an array of elements ['my', 'uncle', 'jumped',
'over', 'the', 'moon']





currently, i'm doing this (in this example, rx_input holds the string
and rx_numbers is the array):



rx_input.gsub!(/[,;\s]/, ' ')

rx_input.squeeze!(' ')

rx_numbers = rx_input.split(' ')



is there a simpler /more elegant/ way of doing this (accounting for the
possibility of double-spaces, etc)?

Or

irb(main):001:0> string = 'my uncle, jumped over; the moon'
=> "my uncle, jumped over; the moon"
irb(main):002:0> string.scan /\w+/
=> ["my", "uncle", "jumped", "over", "the", "moon"]
irb(main):003:0> string.split /\W+/
=> ["my", "uncle", "jumped", "over", "the", "moon"]

Kind regards
