yep. one thing I forgot to mention is that, for the application I'm currently writing (which is basically an ASP cross-reference generator) I
need to have the line number where each block appears. so, the code I'm using is something more like:
sub get_asp_blocks {
my($file) = @_;
open(FILE, $file) or die "can't open '$file': $!\n";
my $dot = 1;
my @blocks = ( ["HTM", $dot, ""] );
my $state = "HTM";
my $last;
while(read(FILE, $char, 1)) {
$dot++ if $char eq "\n";
if($last eq "<" && $char eq "%" && $state eq "HTM") {
chop $blocks[-1][-1];
$state = "ASP";
push(@blocks, ["ASP", $dot, ""]);
} elsif($last eq "%" && $char eq ">" && $state eq "ASP") {
chop $blocks[-1][-1];
$state = "HTM";
push(@blocks, ["HTM", $dot, ""]);
} else {
$blocks[-1][-1] .= $char;
}
$last = $char;
}
close(FILE);
return @blocks;
}
this way, each element of the returned array contains three elements: the type (ASP or HTM), the line number, and the block itself.

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).
