Help with regex	Can't Post

Thanks in advance for any help...

If i have a string containing this data

Code

 $string = qq~header.tpl 
 <!-- BEGIN SUBBLOCK --> 
    I'm in subblock 
       <!-- BEGIN SUBBLOCK1 --> 
          I'm in subblock1 {{HEADER.SUBBLOCK.SUBBLOCK1.ID1}} {{HEADER.SUBBLOCK.SUBBLOCK1.ID2}} 
       <!-- END SUBBLOCK1 --> 
<!-- END subblock --> 
{{ID1}} {{ID2}}~;

how would i use regular expressions to match the text in between  and .

That won't work quite right. You'll succeed too early on the inner end block. Try:

Code

$string =~ m|<!-- BEGIN (\w+) -->(.+?)<!-- BEGIN \1 -->|s; 
my $wanted = $2;

Although I highly dislike use of any permutation of .*?
