計算示例文本的2個給定詞之間的距離

我正在尋找一種方法來輸出距離（空白分隔的詞的量）以在兩個給定的控制檯之間進行控制。考慮以下.txt輸入：計算示例文本的2個給定詞之間的距離

[SEP] Today I went to school for the first time . [/SEP] [SEP] Everyone was excited to see me ! [/SEP]

我現在需要得到在這種情況下[SEP]和[/SEP]之間的距離將是9和6

房地產.txt輸入您可能已經猜到是更長的時間。

UPDATE：我的做法至今（分成數組）：

var text = "[SEP] Today I went to school for the first time . [/SEP] [SEP] Everyone was excited to see me ! [/SEP]"; 
var textArray = text.split(/\[SEP\]|\[\/SEP\]/);

UPDATE：匹配在註釋的正則表達式提供

var text = "[SEP] Today I went to school for the first time . [/SEP] [SEP] Everyone was excited to see me ! [/SEP]"; 
var matchText = text.match("\[[A-Z]+\]([^[]+)\[\/[A-Z]+\]");

UPDATE：使用.exec（）

var myText = \[[A-Z]+\]([^[]+)\[\/[A-Z]+\].exec('[SEP] Today I went to school for the first time . [/SEP] [SEP] Everyone was excited to see me ! [/SEP]')

SEP標籤可以得到多層次？（eq [bla] [sep] bla2 bla3 –

@ mihai.ciorobea好點，但在我的情況下，他們不 – Ilja

@Tushar我的壞，我現在添加的代碼，以將單詞放入數組 – Ilja

嘗試使用split分割文本。這將提供SEP之間的單詞列表。

"[SEP]this is [/SEP] an interesting [SEP] thing[/SEP]".split(/\[SEP\]|\[\/SEP\]/)

之後，您可以用確定

words.length - words.replace(/ /g,'').length

完整的解決方案各組大小：

var wordGroups = "[SEP]this is [/SEP] an interesting [SEP] thing[/SEP]".split(/\[SEP\]|\[\/SEP\]/) 
wordGroups.forEach(function(wordGroup) { 
    wordGroup = wordGroup.trim() 
    if (wordGroup.length == 0) { 
     return 
    } 
    var nrOfWords = wordGroup.length - wordGroup.replace(/ /g,'').length + 1 
    console.log("\"" + wordGroup + "\" has " + nrOfWords + " words") 
})
