Divide the sentence using unique symbols to break it into individual words, while also maintaining

Is there a way to split a sentence with special characters into words while keeping the spaces? For example:

"la sílaba tónica es la penúltima".split(...regex...)

to:

["la ", "sílaba ", "tónica ", "es ", "la ", "penúltima"]
    ↑                     ↑      ↑      ↑
  space                 space  space  space

I've attempted modifying this answer:

Using the code from that answer:

"la sílaba tónica es la penúltima".split(/\b(?![\s.])/)

The result is:

["la ", "s", "í", "laba ", "t", "ó", "nica ", "es ", "la ", "pen", "ú", "ltima"]
              ↑                  ↑                                  ↑

The special characters cause the words to split.

In my attempt, I included the special characters I want to keep (.áéíóúñ,:;?):

"la sílaba tónica es la penúltima".split(/\b(?![\s.áéíóúñ,:;?])/)

The result is:

["la ", "sí", "laba ", "tó", "nica ", "es ", "la ", "penú", "ltima"]
          ↑              ↑                              ↑

Although the characters are included, the words break after them. What would be the correct regular expression for this task?

Answer №1

Consider using the regex pattern \S+\s* to find matches instead of using split method.

var sentence = "the quick brown fox jumps over the lazy dog".match(/\S+\s*/gi);

console.log(sentence);

Answer №2

const phrase = "the stress is on the penultimate syllable".split(" ")

const modifiedPhrase =  phrase.map((word, index ) => {
  if(index!== phrase.length-1) return (word + " ")
  else return word
})

console.log(modifiedPhrase)

Answer №3

This code a-z\xC0-\xff is used to select characters and diacritics. I then split it using /[^a-z\xC0-\xff]/. After that, I insert a space between each character.

Another option would be to split by using /[\s]/

let example = "the stressed syllable is the penultimate".split(/[^a-z\xC0-\xff]/)
for(let j=0; j < example.length; j++){example[j]+= " "; }
console.log(example)
