Match and Extract everything between 2 words in a file

I had posed a similar topic some time back but I want some additional information from the input file.
The log file is as shown...

The main thing to notice in my suggestion was this line:
Expand|Select|Wrap|Line Numbers
  1. my $file = <LOGFILE>;
  2.  
Slurping the whole file into a single var, and then saying...

Expand|Select|Wrap|Line Numbers
  1. while(match){
  2. push $message, $1;
  3. }
  4.  
In your genreport sub you are still testing for a match "one line at a time".

Using the s modifier allows perl's dot character to match all characters INCLUDING a newline. (which is usually the only thing excluded)

And the m modifier changes ^ and $ to represent the beginning and ending of ANY newline, not necessarily the next one.

I noticed in the LOGFILE the chunks were separated by two newlines. THAT would be a good terminator.

I must admit I did forget about the "holdTerminator ". $/
You must undefine that to properly slurp the file.

So...

Just change the DATA to your file handle. "LOGFILE".

One word of caution.
When you slurp, don't do anything else with the data. It takes about as long as assembling an array itself. (If not slightly longer) AND if you then copy the slurped file into an array, you'll have TWO copies on disk.

Using it for this should not be a problem, but just be mindful.
Feel free to Benchmark!
It's your friend.


PS- Code tags use square brackets not angle. :)

PPS- What do ya know? There's a mod on CPAN for this!!

I noticed some lines say [ERROR] but you don't want them.
Just add the "infrastructure :RUN_ID_RUNTIME " back into the regexe.

This should do it:
Expand|Select|Wrap|Line Numbers
  1. while($file =~ /^(\[ERROR\].*?infrastructure:RUN_ID_RUNTIME.*?)\n\n/mgs) {
  2. push(@message, $1);
  3. }

That didn't work. :(

But this did.

Expand|Select|Wrap|Line Numbers
  1. while($file =~ /^(\[ERROR\](?-s:.*)infrastructure:ID_UNHANDLED.*?infrastructure:RUN_ID_RUNTIME.*?)\n\n/mgs) {
  2. push(@message, $1);
  3. }
  4.  
Assuming you want only lines that start with [ERROR] followed by any character EXCEPT a newline, followed by "infrastructure :ID_UNHANDLED", followed by any character INCLUDING a newline, followed by "infrastructure :RUN_ID_RUNTIME ", followed by any character INCLUDING newlines terminating on 2 newlines.

WHEEEWW!!

OK. That successfully filtered these lines from my test:

[ERROR] Undefined

[ERROR] jnjbg

But MATCHED the ones (I think) you want.

Let me know how it comes out!

Hummm....
How are you calling on genreport?
What exactly do you pass to it?
Is it in the current package, or a separate file?

Very strange.

Have you tried KevinADC's code?
It looks like it works too. (using too objectively..:)

I swear my code worked in Komodo with Perl 5.10 on Windows.

Of course I didn't have the exact same logfile to scan.

I am calling it through a batch file in a command prompt in Windows and pass the name of the log file, i.e.

UAESummary.bat AppLog.txt > Report.log


Yes, I tried KevinADC's code too, to no avail.
