How do I extract each words from a text file in scala

it helps some times I'm pretty much new to Scala. I have a text file that has only one line with file words separated by a semi-colon(;). I want to extract each word, remove the white spaces, convert all to lowercase and call them based on the index of each word. Below is how I approached it:
code :
newListUpper2.txt contains (Bed;  chairs;spoon; CARPET;curtains )
val file = sc.textFile("myfile.txt")
val lower = file.map(x=>x.toLowerCase)
val result = lower.flatMap(x=>x.trim.split(";")) // x = `bed;  chairs;spoon; carpet;curtains` , x.trim does not work. trim func effective for head and tail only
result.collect.foreach(println)
val result = lower.flatMap(x=>x.split(";").map(x=>x.trim))

Extract words out of a text file

fixed the issue. Will look into that further This sounds like the right job for regular expressions. Here is some Java code to give you an idea, in case you don't know how to start:
code :
String input = "Input text, with words, punctuation, etc. Well, it's rather short.";
Pattern p = Pattern.compile("[\\w']+");
Matcher m = p.matcher(input);

while ( m.find() ) {
    System.out.println(input.substring(m.start(), m.end()));
}

wish of those help I am working with recursive neural networks and need to process my input text file (containing trees) to extract words. The input file looks like : , You can use re.findall:
code :
import re
with open('tree_file.txt') as f, open('word_list.txt', 'a') as f1:
   f1.write('\n'.join(set(re.findall("[a-zA-Z\-\.'/]+", f.read()))))

How to extract only words from a text file in F#?

With these it helps In F#, items in arrays or lists are separated by the ; (semicolon) character, not the , (comma). Your code is creating an array that contains one 10-item tuple. You should write the following if you want an array of ten items:
code :
let wordSplit (text:string) = 
  text.Split([|' ';'\n';'\t';',';'.';'/';'\\';'|';':';';'|])
  |> Array.toList
let wordSplit (text:string) = 
  text.Split([|' ';'\n';'\t';',';'.';'/';'\\';'|';':';';'|], StringSplitOptions.RemoveEmptyEntries)
  |> Array.toList
