使用Node-ETL

Question

使用node-etl，如果有一个空格分隔符，我可以将文件内容提取到JS数组中：

data.txt

21 Ahmed UK
54 Jean Chine
65 Mourad Tunisia

load.js

var ETL=require('node-etl')
var people=ETL.extract('./data.txt',{
      delimitor:" ", //just ONE Space . What about ONE or many spaces
      headers:["id","name","country"],
 });
 /*
    [
           {id:"21",name:"Ahmed",country:"UK"}, 
           {id:"54",name:"Jean",country:"Chine"},
           {id:"65",name:"Mourad",country:"Tunisia"},      


       ]

 */

现在，如果数据之间的空间不固定（一个或多个）怎么办？什么是合适的分隔符？

data.txt

21 Ahmed                  UK
54                Jean Chine
65        Mourad     Tunisia

Answer 1

实测！

Node-ETL包提供了一些现成的静态分隔符，对于这种情况，ETL.DLM_SPACE_OR_MORE是合适的。

然后，代码应为：

var people=ETL.extract('./data.txt',{
      delimitor:ETL.DLM_SPACE_OR_MORE, //just ONE Space . What about ONE or many spaces
      headers:["id","name","country"],
 });
