Notepad++ Regex - 替换日期中的空格

Question

I have a large export file from a legacy computer system. The dates that get exported have a [space] instead of a 0 for all single digit days or months:

1/ 1/2015 (dd/MM/yyyy)

The first space is not a problem but the second space is.

I have tried to search and replace /[space] but this will replace any occurrences of /[space] in the data file - not only in dates.

I have also tried to use regex find and replace as follows:

Find: / [0-9]/[0-9]+

Replace: /0[0-9]/[0-9]+

The intended out come should be:

Original: 1/ 1/2015

New: 1/01/2015

However I got:

Actual: 1/0[0-9]/[0-9]+

---

Is this even possible in Notepad++ or do I have to use MS Excel?

Thanks

Answer 1

Find : (\\b\\d{1,2}/) +(\\d{1,2})(?=/\\d{4}\\b)

Replace : \\1\\2

Answer 2

Could you try replacing (?<=/) (?=[0-9]/[0-9]+) with nothing (or 0, if you want padded single digit dates)? Works in Sublime, haven't tested NP++.

Answer 3

Try this, was working perfectly in my editor.

Find what: (\\d/)\\s(\\d/\\d{4})
Replace with: $10$2
