Hello,

I know this is done with regular expressions, but I don't know how. I have text file that contains many lines of information. How would I find the line that contains the word "subject:". Then once that line is found how would i get only the text after the colon in to a variable? For example, let say the line is in row 56 and it looks like this: "subject: ORDER CONFIRMATION". How would I find the subject, and how do I get the "ORDER CONFIRMATION". I need to find the subject and only get the subject.

OK, I'm still trying to get better at reg exp myself, but I think I may have the answer to this one.

open FILE, "<textfile.txt";
while (<FILE>) {
     if (/subject\: (.*)/) {
          $whatyouwant = $1;
     }
}
close FILE;

Let me know if that works, I gotta run deal with something so can't test it right now.

Hope this helps,

Jonathan

Hi,

You can use perl system variable $' to extract particular text from the file.

I have something smiliar question in perl.
I have a text file, and I would like to search a "1234", but would like to display the keyword from the text file of the number.

------------
Number: 1234
Keyword:
Will do the same
Comment: No need to take action

Number: 2345
Keyword:
Hello World
Comment: Just say Hi

I know the Number: 1234, so I can use "grep to search the number"
But I would like to display the Keyword corresponding to the Keyword.
