( #3333=superdoc: print w/replies, xml ) Need Help??

Ummm, I have no problem doing the substitution using the code supplied:

$line = "She was very absorbed in her homework."; $word = "absorb"; print STDOUT "Line: $line\n"; $line =~ s/($word(?:s|ed))/<b>$1<\/b>/igm; print STDOUT "New Line: $line\n"; print STDOUT "\$1 contains: $1\n";

Of course, I might consider changing it slightly to read:

$line =~ s/\b(${word}(?:s|ed)?)\b/<b>$1<\/b>/igm;

However, I did just discover that there is something more going on here, because while the original (without the \b) does set something in $1, my change doesn't (despite doing the substitution properly).

And finally, if you're just doing a match why are you using s///?

      Should cpanminus be part of the standard Perl release?
