Removing repeated words in a string

[Wibbly]

Anyone know how to write an expression to remove the second instance of repeated words where they exist in a string?

Suppose string1 = "It's going to rain in 10mins in London London". I want string2 = "It's going to rain in 10mins in London"

Something like this should work:

Code: Select all

string2 = replaceAll(string1, '(\\b\\S+\\b)\\s+\\b\\1\\b', '$1');
