如何在字之间或行之间进行搜索？

Question

如何找到文件中单词之间或“startString”和“endString”行之间的所有行？const fs = require('fs')const startString = '-----CompilerOutput:-stderr----------'const endString = '-----EndCompilerOutput---------------'const file = fs.readFileSync('./history.log', 'utf8')let arr = file.split(/\r?\n/);arr.forEach((line, idx)=> {    if(line.includes(startString, endString)){        console.log((idx+1)+':'+ line);    }})

您可以对文件进行切片：

const startIndex = file.indexOf(startString) + startString.length;

const endIndex = file.indexOf(endString);

const between = file.slice(startIndex, endIndex);

console.log(between);
