Re: Regular expressions (regex) question for parsing

Hi, I'm looking for some ideas on the best way to parse blocks of text that is formatted such as:

$sometext %\r\n                        -- good data       $otherstring %\r\n                        -- good data
$andyetmoretext %\r\n                    -- good data
$finaltext                                 -- bad data (missing ending)

Each line should start with a $dollar sign, then some arbitrary text, ends with a percent sign, followed by carriage-return and line-feed. Sometimes though, the final line is not complete. In that case, I want to save those lines too. ....so that I end up with an array like:

$result = array (    "matches" =>
        array (    0 => "$sometext %\r\n",
                1 => "$otherstring %\r\n",
                2 => "$andyetmoretext %\r\n"
                ),
    "non_matches" =>
        array (    3 => "$finaltext"
                )
            );

The key thing here is that the line numbers are preserved and the non-matched lines are saved... Any ideas, what's the best way to go about this? Preg_matc, preg_split or something incorporating explode? ....Rene

Where does the text come from, a text file? client-side textarea? DB? etc.?
