this function reads an ASP file (yes, sometimes I have to fight with such stuff) separating code blocks from HTML blocks. the function returns an array where each element is a 2-element array. the first element is either "HTM" or "ASP", and the second one is the block itself. ASP tags (<% and %>) are removed.

cheers,
Aldo

sub get_asp_blocks {
    my($file) = @_;
    open(FILE, $file) or die "can't open '$file': $!\n";

    my @blocks = ( ["HTM", ""] );
    my $state = "HTM";
    my $last;
    while(read(FILE, $char, 1)) {
        if($last eq "<" && $char eq "%" && $state eq "HTM") {
            chop $blocks[-1][1];
            $state = "ASP";
            push(@blocks, ["ASP", ""]);
        } elsif($last eq "%" && $char eq ">" && $state eq "ASP") {
            chop $blocks[-1][1];
            $state = "HTM";
            push(@blocks,  ["HTM", ""]);
        } else {
            $blocks[-1][1] .= $char;
        }
        $last = $char;
    }
    close(FILE);
    return @blocks;

In reply to parsing an ASP file by dada

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.
