退格分隔的平面文件 [英] Backspace delimited flat files

问题描述

有没有人看过以空格分隔的平面文件？我的要求是解析这样的文件，但是我无法在文件中放入退格字符以检查是否能够检测到它。

Has any one ever seen a backspace delimited flat file? My requirement is to parse such a file but I am not able to put a backspace character into a file to check if I am able to detect it.

推荐答案

拆分应该比使用任何其他定界符更难。毕竟，这只是另一个角色。在Python中，例如：

Splitting shouldn't be any harder than using any other delimiter. It's just another character, after all. In Python, for instance:

>>> x = "apples\bbanana\bcoconut\bthese are delicious!"
>>> x.split('\b')
['apples', 'banana', 'coconut', 'these are delicious!']

大多数语言都使用 \b 作为退格符。如果不是，则还可以包含退格符本身的ASCII控制代码，即\x08。

Most languages use \b as the escape character for a backspace. If yours doesn't you can also include the ASCII control code for backspace itself, which is \x08.
