. That's a possibility. I was also thinking that maybe mod_perl was built against a different version of Perl, possibly one that has a problem with this particular regex which was fixed in a later version. both mod_perl and the script are using the debian packaged perl/libperl, the perl -V dump

Re: slow regex [BENCHMARK]

under mod_perl this takes 23 seconds. running the perl by hand (via extracting this piece into a seperate perl script) on the same data takes less than 1 second. Are you sure that the string you're regex'ing is the same in both cases? Why are you using the /o operator? CG isn't a variable,

Regex problem

Hi all, Can somebody show me how to use regular expression to subtitute a string with speacial character such as [* , ?] in it ? for example $string = 'test ? test'; $input = 'Start test ? test End'; $change = 'Change'; $input =~ s/$string/$change/g; After change, I expect $input = 'Start

Re: Regex problem

The regex engine is seeing extra stuff in $string and thinking that you are trying to build an expression with it. To get Perl to handle $string as straight text, you need to quote it like this: $input =~ s/\Q$string\E/$change/g; Rodney Broom

Hi all... I posted to the list a little while ago a simple regular expression PerlHandler implementation. I've cleaned it up since then and thought I might post it to CPAN if there is any interest. I was thinking of Apache::Regex as the release name. I know it's a basic module
