Regex: Is it possible to reference all of the repeats of a capture?
Consider this regex: ^([0-9]+)(?: ([-\+/%\*]) ([0-9]+))+$
In english, it says "a number, followed by one or more of (an operation and another number)".
Matched against a subject like 5 + 4
that regex produces $1 = 5, $2 = +, and $3 = 4.
Matched against this subject: 5 + 4 * 3
, I get $1 = 5, $2 = *, and $3 = 3.
In this latter case, can I capture and reference the + and the 4 ?
In other words, when using a quantifier in the regex, can I reference sequences other than the fin开发者_C百科al captured sequence?
If the answer depends n the language or platform, I guess I am most interested in:
- C, with PCRE
- Javascript
- .NET, with System.Text.RegularExpressions
In .NET, you would use
myMatch.Groups[1].Captures
