使用 Node-ETL 的一个 space 或多个合适的定界符

Suitable Delimitor for one space or more using Node-ETL

使用 node-etl ,如果一个 space 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 space 不固定(一个或多个)怎么办?什么是合适的分隔符?

找到了!

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。

那么,代码应该是:

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"],
 });
