Re: Parsing ASP files

Yup, i'm pretty sure you'll have to preprocess

You can glean some regexes from http://search.cpan.org/~johnd/ASP4-1.073/

http://cpansearch.perl.org/src/JOHND/ASP4-1.073/lib/ASP4/PageParser.pm

#!/usr/bin/perl --
use strict; use warnings;

my $asp = <<'__HTML__';
<input value="abc" /> abc &nbsp; abc
<% abc ( '<input value="abc" /> abc &nbsp; abc <span> %>', $abc ); %>
__HTML__



use HTML::Tree;
my $t = 'HTML::TreeBuilder'->new;
$t->ignore_unknown(0);

$t->parse( $asp ); $t->dump; print "\n\n";


$asp =~ s{
    <%
    ((?:
        '[^']+'
        |
        "[^"]+'
        |
        \$?[\w\s\(\);,]+
        |
        [^%]+
    )+)
    %>
}{
    my $content = $1;
    HTML::Entities::encode_entities( $content );
    qq'<yoASP content="$content">'
}gsex;

$t->parse( $asp ); $t->dump; print "\n\n";

#~ and reverse it
$asp =~ s/<yoASP content="([^"]+)">/
    my $content = $1;
    HTML::Entities::decode_entities( $content );
    $content;
/gsei;
print "$asp\n\n";

Awesome! The test script is now working great: #!/usr/bin/perl use HTML::PullParser; use HTML::Entities; my $doc = <<'EOF'; my %options = (); <input value="abc" /> abc   abc <% abc ( '<input value="abc" /> abc   abc <span> %>', $abc ); %> EOF $doc =~ s{ <% ((?: '[^']+' \| "[^"]+' \| \$?[\w\s;,]+ \| [^%]+ )+) %> }{ my $content = $1; HTML::Entities::encode_entities ( $content ); qq'<asp_pp content="$content">' }gsex; foreach ( qw{ start text default } ) { $options{$_} = "'$_', text, tagname, attr"; } my $p = HTML::PullParser->new ( doc => $doc, %options ); my $output = ""; while ( my $token = $p->get_token() ) { my $text = $token->[1]; $text =~ s\|abc\|<b>abc</b>\|g if $token->[0] eq 'text'; $text = "<%$token->[3]->{content}%>" if $token->[0] eq 'start' and $token->[2] eq 'asp_pp'; $output .= $text; } print $output; [download] Arnon Weinberg Back2Front - The Web Site People	[reply] [d/l]

Looks like I spoke too soon. For anyone else attempting something similar, the above code had a flaw illustrated by the last line I added to the $doc test string below. The solution I came up with essentially amounts to using a more benign format for the temporary replacement string used to hide ASP code from HTML::Parser: #!/usr/bin/perl use HTML::PullParser; use HTML::Entities; my $doc = <<'EOF'; my %options = (); <input value="abc" /> abc   abc <% abc ( '<input value="abc" /> abc   abc <span> %\>', $abc ); %> <input value="<%= $abc %>" abc /> EOF $doc =~ s/<%(.*?)%>/ my $content = $1; HTML::Entities::encode_entities ( $content ); qq'[[asp_pp"$content"asp_pp]]' /gsex; foreach ( qw{ text default } ) { $options{$_} = "event, text, is_cdata"; } my $p = HTML::PullParser->new ( doc => $doc, %options ); my $output = ""; while ( my $token = $p->get_token() ) { my $text = $token->[1]; $text =~ s/(\[\[asp_pp"[^"]+"asp_pp\]\])\|(abc)/$1?$1:"<b>$2<\/b>"/gs +e if $token->[0] eq 'text' and ! $token->[2]; $output .= $text; } $output =~ s/\[\[asp_pp"([^"]+)"asp_pp\]\]/ "<%" . HTML::Entities::decode_entities ( $1 ) . "%>"/gse; print $output; [download] Output: `<input value="abc" /> <b>abc</b>   <b>abc</b> <% abc ( '<input value="abc" /> abc   abc <span> %>', $abc ); %> <input value="<%= $abc %>" abc />` [download] Arnon Weinberg Back2Front - The Web Site People	[reply] [d/l] [select]
