REGEX exclude if there's a dash before number and if inside other string
I've been trying to write a regular expression that does exactly as stated in the title. I need to find all occurences of xA, or xkA, or xmA (and variation eg. x k A or xk A) to format those amperes later on: x A, x kA, x mA.
Unfortunately with the regex I have it selects number+A whenever it finds it:
F-2A WACEGF2AOKR 10m A AC
F-3A WACEGF3AOKR 10k A AC
C-7A WACEGC7AOKR 20m A
My regex:
([0-9]+)([m|k])? ?A
I found some solution online:
[^- a-zA-Z]([0-9]+)([µ|µ|m|M|k|G|]) ?A
but it fails while run in Dreamweaver (and I HAVE TO use it in DW, it's part of bigger command) - it "eats" part of the string in the backreference, making eg. "10" out of "1000"
Edited:
\b([0-9]+)([µmMkG]|µ)\s*A
(?<![0-9])([0-9]+)([µmMkG]|µ)\s*A
The first one selects as follows:
The second one doesn't select anything :(
Note I am trying not to remove the char before the number, i.e. > or / that are removed if I use the following:
You may use the following regex:
(^|[^\w-])\b([0-9]+)([µmMkG]|µ)? ?A
When replacing, mind you may access the text captured with capturing groups using $ + a digit identifying the group. E.g. (^|[^\w-]) text is access via $1, ([0-9]+) text is accessed via $2, ([µmMkG]|µ) can be reached via $3.
See the regex demo.
Details
(^|[^\w-])- Group 1: start of string or any char other than letters, digits, underscore and-\b- a word boundary([0-9]+)- Group 2: one or more digits([µmMkG]|µ)?- Group 3 (optional):µ,m,M,k,Gorµ?A- an optional space and thenA`.
