zeroc00l has asked for the wisdom of the Perl Monks concerning the following question:

Hi all! I'm a newbie on Perl for a problem here at work that need it. I must import 1200 html files from the old site to the new site, made with joomla, I found a perl script that tries to import everything except the date, this script uses tha creation date of the files....as you can imagine this is my problem, I want that the script import the date printed in every html file in a tag that I declared as  <date>...</date>
I pass firstly the files with a php function I wrote to elminate everything I don't need from the html files, so I obtain a plain file with just the <title>....</title><p><date>...</date> the text of the new</p>
Ok....now I use the perl script to generate the importing of all these files into joomla and everything goes fine except that the edit I made doesn't function as I expect.. I post here all the function under the code tag. PS: the function i maded by Paco Hope.

#!/usr/bin/perl =pod =head1 BulkImport.pl - Import plain HTML files into Joomla database =head1 SYNOPSIS This script imports HTML files directly into Joomla's database. It works with both Joomla 1.0.12 and Joomla 1.5rc1 =head1 DESCRIPTION This script reads a directory to find all the HTML files and imports t +hem into a Joomla site. It reads the content of the HTML page and loo +ks at the <title> tag to determine the title of the page. It looks at + the file’s modification date to determine the “publication date” for + Joomla, and then it makes a MySQL database connection and executes t +he query. I hacked the original script together in about an hour. It probably wo +rks, but it is not for the faint of heart. If you barely understand J +oomla, and you’ve never looked at perl before, and you’re working fro +m a Windows PC, this isn't ready for you yet. If you’re using a Mac o +r Linux, or you’re comfortable running Perl on Windows, this is prett +y straightforward. =head1 OPTIONS This program takes the standard 2 options. =over 6 =item B<-n> Dry run. Don't do anything. Just show what would be done. It won't con +nect to the database, it won't insert any files. It will just show you the nam +es and dates of all the files that it would try to insert. =item B<-D> Old Database. Use the 1.0.12 database schema. Otherwise, the 1.5 schem +a is assumed. Use this option if you use Joomla 1.0.12. =item B<-r> Recurse. Descend subdirectories and find all their files and import th +em, too. Otherwise, subdirectories are skipped and only the files in directory +are inserted into the site. =item B<-f> Use the file name as the title, not the <title> from inside the file. +The current regular expression will strip off '.(asp|aspx|htm|html|shtm|sh +tml)' and use the remaining file name. =item B<-F> B<Append> the filename to the title of the page. For example, if the p +age contains <title>New Page 1</title> and it is named I<menu.htm>, t +hen this will set the title (in Joomla) to be "New Page 1 menu". Agai +n, as in B<-f>, common file extensions are stripped off. =back =head1 OUTPUT You'll see a line or two for each file processed. =head1 ERRORS The script blows up on errors. More details will follow. =head1 DIAGNOSTICS HTML files that have no <title> tags will be named "Article" unless B< +-f> or B<-F> are used. If you use the wrong database type (e.g., you forget to specify B<-D> +when you should), it will blow up at the SQL level, but keep on truckin. In oth +er words, you'll get lots and lots of errors. =head1 EXAMPLES perl BulkImport.pl -r html =over 2 This will go into the B<html> directory and find pages and upload them +. Because of B<-r>, it will descend into any subdirectories that are fou +nd and process HTML files there, too. =back =head1 AUTHOR Paco Hope <paco@paco.to> =head1 COPYRIGHT Copyright (C) 2007 Paco Hope <paco@paco.to> Distributed under the BSD +License.

    Could you try and
    1)reduce the code size by eliminating (seemingly) non relevant parts of code (e.g. database handling)
    2) re-format the problem statement for clear understanding

    my ( $dev, $ino, $mode, $nlink, $uid, $gid, $rdev, $size, $atime, $mtime, $ctime, $blksize, $blocks ) = stat($file); my ( $sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $isdst ) + = localtime($mtime); # make a MySQL compatible date my $mysqlDate = strftime( "%F %T", $sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $isdst );
    Try replacing this code with acquiring of the date you parsed from <data> tags ($j::date). You may need to parse and reformat the date, have a look at Date::Parse, localtime and strftime.
    Sorry if my advice was wrong.
      Hi, thank you for the reply, but perhaps my question was malformed, I try to be more clear: With that script everything goes well except the return of the date inside the tag <date>...</date> I presume that the problem is in this subfunction I replicated from the subfunction that try to get the Title of the page:
      # this first bit is right out of the HTML::Parser perldoc sub title_handler { return if shift ne "title"; my $self = shift; $self->handler( text => sub { $j::title = shift }, "dtext" ); $self->handler( end => sub { shift->eof if shift eq "title"; }, "tagname,self" ); } sub date_handler { return if shift ne "date"; my $self = shift; $self->handler( text => sub { $j::date = shift }, "dtext" ); $self->handler( end => sub { shift->eof if shift eq "date"; }, "tagname,self" ); }
      And then when I call it:
      sub insertFile { my $file = shift; my $p = HTML::Parser->new( api_version => 3 ); $p->handler( start => \&title_handler, "tagname,self" ); $p->handler( start => \&date_handler, "tagname,self" ); $p->parse_file($file); .................
      If I delete the call to date, the Title subfunction goes well, but I lost the date, on the other side if I left everything as I modified, the date goes well but I lost the Title. I hope that now is more clear.....:)
        Try running your code in the debugger. Does the $j::date variable get assigned? Perhaps you need it to look like the old one (I mean, the same format, try Date::Parse and strftime("%F %T",str2time($j::date))).
        Sorry if my advice was wrong.
