本文介绍了正则表达式CSV替换引号之间的逗号的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我们有这样的字符串:

"COURSE",247,"28/4/2016 12:53 Europe/Brussels",1,"Verschil tussen merk, product en leveranciersverantwoordelijke NL","Active Enro"

目标是替换merk,product之间的逗号,并保留逗号,和,&,,以便我们可以正确地分割文件。

The Goal is to replace the comma between "merk, product" and to keep the comma like "," and ", & ," so we can split the file correctly.

有任何建议吗?

感谢

推荐答案

首先,您应该检查 了解CSV文件及其在ABAP中的处理

First of all, you should check Understanding CSV files and their handling in ABAP article.

对于一次性作业,您可以使用此正则表达式(但请注意,对于较长的字符串,它可能无法正常工作,使用它作为最后手段):

For a one-time job, you can use this regex (but note that with longer strings, it may not work well, use it as a means of last resort):

,(?!(?:[^"]*"[^"]*")*[^"]*$)

请参阅 regex演示< a>
