使用正则表达式将字符串拆分为不包括单词的数组

Question

There was a question asked today, that piqued my interest (and subsequently was deleted) where the user wanted to split the following string with a regular expression

'The 1. cat 2. sat 3. on 4. the 5. mat';

into this array

["cat","sat","on","the","mat"]

there were answers with this expression

str.match(/[a-z]+/gi);

which of course returns

["The","cat","sat","on","the","mat"]

The nearest I come come to an answer was with

str.match(/[^The][a-z]+/gi);

which returns

[" cat"," sat"," on"," the"," mat"]

Unit tested here

Of course this can be done, but how?

Answer 1

How about

Javascript

var str = 'The 1. cat 2. sat 3. on 4. the 5. mat',
    arr1 = str.match(/[a-z]+/gi),
    arr2 = str.match(/\b[a-z]+/g);

console.log(arr1);
console.log(arr2);

Output

["The", "cat", "sat", "on", "the", "mat"] 
["cat", "sat", "on", "the", "mat"]

Answer 2

str.match(/\b(?!The\b)[a-z]+\b/gi)

Answer 3

您可以使用此模式：

str.match(/\b[a-z]+\b(?!\s1\.)/gi)
