Hi Monks!

I am trying to change some things on file names I have in my project but the last one is a kill; replace the last part of the file name only if it ends with "_00001". I am trying to do this in one regular expression line, can I add some sort of conditional to the regexp to do this? here is a code sample: 
my $rd = int( rand(100000)) + 999999;

my $filename = "XYZ12345_X05_20110805_9999999_00001.TXT";
#my $filename = "XYZ12345_X05_20110805_9999999.TXT";

#add dash between $3 and $4 to the .txt before processing them:::
#pad $2 with 0s

#replace the end of the file with a randon number if the filename ends
+ with _00001

(my $xrenamed = $filename) =~s/(^\w{3})(\d{5,7})(_\w{1})(\w{1,2}_)(\d{
+8}\_)(.*)/$1.sprintf("%07d",$2).$3."-".$4.$5.$rd.".txt"/ie;

#
print "\n\nFILE = *1- $1 * 2 - $2* 3 - $3* 4 - $4* 5 - $5* 6 - $6* - $
+xrenamed\n\n";
