I need to extract footnotes from a very long LaTeX document. I would

Next, I decided to try to write a Perl script, and that's the point at
which I presently find myself.
The Text::Balanced module is perfect for this. Here's how I might do it
using that module:
use strict;
use warnings;
use Text::Balanced qw(extract_bracketed);
use Data::Dumper;
my $text = q(
Some text.
\footnote{My \bold{nice} footnote is here.}
More text is here.
\footnote{Second footnote \italic{\bold{i}tem}.}
Final text.
);
$text =~ s/^ {4}//mg; # probably superfluous
# Start working on the text.
my @footnotes;
my $extracted;
while ($text =~ s/.*?(\\footnote)//s) {
($extracted, $text) = extract_bracketed($text, '{}');
push @footnotes, $1 . $extracted;
}
print Dumper([EMAIL PROTECTED]);
I know my Latex probably sucks because it's been years since I've had to
do it, but I hope this helps.
