Question

我有大量文件（1700万行），其中包含以下格式的内容：

"AB101XG","57.144165160000000|","-2.114847768000000|";
"AB106RN","57.137879760000000|","-2.121486688000000|";
"AB107JB","57.124273770000000|","-2.127189644000000|";
"AB115QN","57.142701090000000|","-2.093014619000000|";
"AB116UL","57.137546630000000|","-2.112695886000000|";
"AB118RQ","57.135977620000000|","-2.072114784000000|";
"AB123FJ","57.098002900000000|","-2.077668775000000|";
....

减小尺寸，因为不需要我想在每个|之前删除最后7个数字不应删除其他数字等。

任何想法，如果有所作为，我正在使用Textpad

谢谢，Neil

Answer 3

用于说明所需模式的Javascript示例。

var line = '"AB101XG","57.144165160000000|","-2.114847768000000|';

var result = line.replace(/\d{7}\|/, '|');

result ; //# =>  "AB101XG","57.14416516|","-2.114847768000000|

仅匹配前7位数后跟|
