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

I have to edit an html file. The problem is I have to delete a whole paragraph depending on certain pattern recognition and then add another para with some other text at some other location in the file. How do I delete a whole para and then add another one at some other location? Thanks!!

    With such a description we can give only general advice (also smells a bit like homework), see perlrun, for, split and perlop: 
    /usr/bin/perl -i.bak

@pars= split /\n\n/, join '', <>;
for( @pars ){
  next if /pattern1/;
  print $newpara if /pattern2/;
  print;
  print "\n\n";
}
