Re^2: regex not working

[gwhite]

If I only want up to the . and it does not always appear (different databases return different format strings for that portion of the date/time) will this:

/^(\d+)-(\d+)-(\d+) (\d+):(\d+):(\d+)/

get it done? I am a regex incompetent.

To me this last expression will not match if a . is indeed present.

So if you don't know wether or not the milliseconds have a decimal part or not you could do :

 /^(\d+)-(\d+)-(\d+) (\d+):(\d+):(\d+(?:\.\d+)?)$/

$6 will then hold the ms, with or without the optional decimal part.

What about the rough regex:

/^.*?(\d+)\D(\d+)\D(\d+)\D(\d+)\D(\d+)\D((\d+)\.?(\d*)+)\D?/;

which takes care to match 6 times digits delimited in some way?

So you'll always get the:

($year, $month, $mday, $hour, $minutes, $seconds) = ($1, $2, $3, $4, $5, $6);

Yes, that will do exactly as you've stated. This is where you can try it yourself in a simple test case:

while ( chomp($_ = <DATA>) ) {
    print /^((\d+)\-(\d+)\-(\d+)\s+(\d+):(\d+):(\d+))/ ?
        "Matched on '$_': $1\n" : "Unmatched on '$_'\n";
}

If you want only up to '.' then use $7 instead of $6.
