Regular Expression

Question

Currently working on a string in C#.

Example:

07.02.2011 17:24:17 [/sbc_DIG] [ERROR] CommandExecutionService:290 - Error during command execution

I can't split using spaces as in somecase there will spaces inside squarebracet

In this case I'm interested in getting 07.02.2011, 17:24:17 and CommandExecutionService:290 using regex

---

Solution based on Ikegami answer

@"^(?[0-9.]+) (?[0-9:]+) [.?] [.?] (?[a-zA-Z0-9:]+)\s";

Answer 1

Using Perl syntax, but the regex pattern should be the same in C#,

my ($date, $time, $pos) = $line =~ /
   ^
   (\S+) \s+
   (\S+) \s+
   \[ [^\]]* \] \s+
   \[ [^\]]* \] \s+
   (\S+)
/x;

Answer 2

Why not just split on spaces for the first four fields and then take the first word of the last field?

It looks like your data is really structured like:

<date>(space)<time>(space)<URL?>(space)<severity/log level>(space)<message>

So just split it into those components by splitting on spaces:

string[] fields = myString.split(" ", 4);
