Hi!! First, I don't know anything about Ruby.. But i am trying to do "Find/Search and Replace" but searching into a word. For example: "Hello word", "e" will be replaced by "3". So, "H3llo word". Is this possible?? Thanks!! And sorry about my bad english

The string class has the methods :sub and :gsub, which replace ("substitute") based on following logic:





For more complex substitutions you need to use a regexp pattern.

Code: Select all

mystring = "Hello World".sub("e", "3") # results in "H3llo world"
mystring = "Hello there".sub("e", "3") # results in "H3llo there"

Code: Select all

mystring = "Hello there".gsub("e", "3") # results in "H3llo th3r3"

Thanks you very much!!!
