Two problems:

Missing space in 

if rather than while

A working version of your code in a form that is better for stand alone testing is:

use strict;
use warnings;

my $text = join "", <DATA>;
while($text =~ /<!-- Start_of_revision-->(.*?)<!-- End_of_revision-->/
+sg)
    {
    print $1;
    }
    
__DATA__

<!-- Start_of_revision-->
revision1
<!-- End_of_revision-->

<!-- Start_of_revision-->
revision2
<!-- End_of_revision-->

<!-- Start_of_revision-->
revision3
<!-- End_of_revision-->

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
