Hi, I am trying to construct a regular expression to search and replace a file. The following is the script. #!use/bin/perl use strict; use warnings; my $line = $ARGV[0]; my $find = "[^a-zA-Z0-9]+seqfile[^a-zA-Z0-9]+=[^a-zA-Z0-9]+[a-z]+.."; my $replace = "done"; open (FILE, ">>/home/user/Desktop/test") || die "cant open file \n"; ...
For the love of God I am not getting this easy code to work! It is always alerting out "null" which means that the string does not match the expression. var pattern = "^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$"; function isEmailAddress(str) { str = "[email protected]"; alert(str.match(pattern)); return str.match(pattern...

How can I match everything with a PHP regular expression? I tried: /[.\r\n]*/, but it isn't working. Any ideas? Thanks. This is for a method I made for a PHP class to parse e-mails: public function getHeader($headerName) { preg_match('/[\r\n]' . $headerName . '[:][ ](.+)[\r\n][^ \t]/Uis', "\n" . ltrim($this->originalMessage), ...

I've been parsing poker hand histories for the past year and have learned quite a deal about parsing in general. We started with regexes but quickly realized that wouldn't scale easily. We skipped languages from ruby to c++ and finally came to grips that it was the algorithim that had to change. We picked up Boost::Spirit and watched o...

I am saving user-submitted HTML (in a database). I must prevent Javascript injection attacks. The most pernicious I have seen is the script in a style="expression(...)". In addition to this, a fair amount of valid user content will include special characters and XML constructs, so I'd like to avoid a white-list approach if possible. (L...
Hello, I'd like to be able to parse date and times out of a log file. Currently they're in the following format: "02/Jun/2009:14:38:50" but i'd like to separate them in different columns using something available from a linux command line so that the resulting output looks as follows: "02/Jun/2009" "14:38:50" could someone please sh...

Ok, i'm a regex doofus. I only ever learn enough to get me by, but i would like to know how to do the below regex without using a php ternary operator in the middle of it.

Is it possible to detect repeated number patterns with a regular expression? So for example, if I had the following string "034503450345", would it be possible to match the repeated sequence 0345? I have a feeling this is beyond the scope of regex, but I thought I would ask here anyway to see if I have missed something. ...
I need a regex to do the following (unfortunately it has to be a regex, I can't code this because it's working within a purchased product): I'd like to select all image tags in a chunk of html where either the image tag does not contain a class attribute, or, if it does contain a class attribute, that attribute does not contain a specif...
