in thread A complex recursive regex,help

Hi ,

The cases where the xx appears last are clearly taken care of by your regex BrowserUk,the part I am not understanding is that you are saying that it will fall over if yout date containes any occurances of xx without |'s or x's on either side, please give an instance of this BrowserUk, in terms of data to facilitate the understanding as yoru regex is doing pretty good in all data strings

    An example where mine falls over, but I think tachyon's wouldn't.

    $t = "xyxxy|xx|xy|xx|yy|yxxy xx x" $t =~ s[(?<!x)(x)(x)(?!x)][$1 $2]g; print $t xyx xy|x x|xy|x x|yy|yx xy x x x

    Examine what is said, not who speaks.

    The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.
