Regexp query

[poolboi]

hey guys,

this is one regexp i did and it worked
but i dunno if it's correct
could anyone verfy

for the sentence in the file

/* 1 TB Hi VTP-10 SESSION=01471 USERID=##$@@# STARTED 2008-05-09 09:17:00 */

i want to match things between 1 TBHLR to USERID

so i used this
[CODE=perl]
if ($data1 =~ /1 TBHLR.+USERID/)
[/CODE]

is this matching alright?

The pattern you have used will match lines containing '1 TBHLR' followed by one/ more characters and then followed by 'USERID'. But if you want to extract characters between these two expressions, you have to group those characters and assign it to a variable as follows:

open(FILE,"data.txt") or die "opening file failed";
while(<FILE>)  {
if(/1 TBHLR(.+)USERID/)  {  ## group characters i between using parantheses
  my $content=$1;  
# $1 is the special variable carrying pattern matched inside
# parantheses number 1.  
  print "$content\n";   ### you can even print $1 directly
}
}

There is no 'TBHLR' in the sample line that you provided :)

thanks!

yup.. i change my code forgot to change the TBHLR part
so since this syntaxt matches then i guess it's alright
just wanna get opinions if the syntax correct
