Rename HTML files with title tag

February 13, 2006 10:11 PM

I have a large number of HTML files with numeric names (001.html, 2990.html, etc.). I would like to have each file renamed with text drawn from each file's HTML title tag.

I have searched high and low for a way to do this, but have not been successful. Anyone know of any scripts or apps that can do this?

I'm not very familiar with the program, but I'm willing to bet that you can somehow get AutoIt to do it for you.

Best answer: Because I like a challenge... here's a perl script to do it (tries to avoid shell meta characters and duplicates):

#!/usr/bin/perl -wuse strict;use File::Find;use File::Spec::Functions qw/rel2abs :DEFAULT/;use HTML::TreeBuilder;if (@ARGV != 2) {    print STDERR "usage: ./html-rename <in dir> <out dir>\n";    exit 1;}my $in = rel2abs( shift );my $out = rel2abs( shift );find( \&wanted, $in );sub wanted {    my ($fname, $tree, $title, $count);    return unless /\.htm(l)?$/;    $tree = HTML::TreeBuilder->new_from_file( $_ );    if ($title = $tree->look_down( '_tag', 'title' )) {        $fname = $title->as_text . '.html';        $fname =~ s/[\|&`\$\*\?~]//g;    } else {        $fname = $_;    }    if (-e catfile( $out, $fname )) {        print STDERR "DUPLICATE: $fname\n";        return;    }    link $_, catfile( $out, $fname );    $tree->delete;}

What OS are you using?

BASH oneliner:

for x in `ls *.html`; do foo=`grep '##'`; mv $x $foo2.html; echo $foo2;done

Note that this has no error checking and will fail on pages where the title has funky characters like spaces in it.
