• 使用readLine库按行解析

var fs = require('fs');
var readLine = require('lei-stream').readLine;

const cityArr = {};
readLine('./myfile.txt').go(function (data, next) {
    let _tmpArr = data.split('	');
    if(_tmpArr[0] && !(_tmpArr[0]%10000)){
        console.log(_tmpArr[0]%10000);
        console.log('市');
        cityArr[_tmpArr[1]] = {};
        cityArr[_tmpArr[1]].name = _tmpArr[2].replace('\r', '');
        cityArr[_tmpArr[1]].areaArr = [];
    }

    if(_tmpArr[0] && (_tmpArr[0]%10000) && !(_tmpArr[0]%100)){
        console.log('区');
        cityArr[_tmpArr[0]].areaArr.push({
            name: _tmpArr[1],
            code: _tmpArr[2].replace('\r', '')
        });
    }
    
    next();
}, function () {
    fs.writeFile('res', JSON.stringify(cityArr));
    console.log('end');
});
