DESCRIPTION
This module is to copy a HTML file without beaking links in the file. This module is a sub class of HTML::Parser.

REQUIRED MODULES

HTML::Parser

CLASS METHODS

  htmlcopy
    HTML::Copy->htmlcopy($source_path, $destination_path);

Parse contents of $source_path, change links and write into $destination_path.

  parse_file
    $html_text = HTML::Copy->parse_file($source_path,
                                        $destination_path);

Parse contents of $source_path and change links to copy into $destination_path. But don't make $destination_path. Just return modified HTML. The encoding of strings is converted into utf8.

CONSTRUCTOR METHODS

  new
    $p = HTML::Copy->new($source);

Make an instance of this module with specifying a source of HTML.

The argument $source can be a file path or a file handle. When a file handle is passed, you may need to indicate a file path of the passed file handle by the method "source_path". If calling "source_path" is omitted, it is assumed that the location of the file handle is the current working directory.

INSTANCE METHODS

  copy_to
    $p->copy_to($destination)

Parse contents of $source given in new method, change links and write into $destination.

The argument $destination can be a file path or a file handle. When $destination is a file handle, you may need to indicate the location of the file handle by a method "destination_path". "destination_path" must be called before calling "copy_to". When calling "destination_path" is omitted, it is assumed that the locaiton of the file handle is the current working directory.

  parse_to
    $p->parse_to($destination_path)

Parse contents of $source_path given in new method, change links and return HTML contents to wirte $destination_path. Unlike copy_to, $destination_path will not created and just return modified HTML. The encoding of strings is converted into utf8.

ACCESSOR METHODS

  source_path
    $p->source_path
    $p->source_path($path)

Get and set a source location. Usually source location is specified with the "new" method. When a file handle is passed to "new" and the location of the file handle is not the current working directory, you need to use this method.

  destination_path
    $p->destination_path
    $p->destination_path($path)

Get and set a destination location. Usually destination location is specified with the "copy_to". When a file handle is passed to "copy_to" and the location of the file handle is not the current working directory, you need to use this method before "copy_to".

  enchoding
    $p->encoding;

Get an encoding of a source HTML.

  io_layer
    $p->io_layer;
    $p->io_layer(':utf8');

Get and set PerlIO layer to read the source path and to write the destination path. Usually it was automatically determined by $source_path's charset tag. If charset is not specified, Encode::Guess module will be used.

  encode_suspects
    @suspects = $p->encode_sustects;
    $p->encode_suspects(qw/shiftjis euc-jp/);

Add suspects of text encoding to guess the text encoding of the source HTML. If the source HTML have charset tag, it is not required to add suspects.

  source_html
    $p->source_html;

Obtain source HTML's contents

NOTE
Cleanuped pathes should be given to HTML::Copy and it's instances. For example, a verbose path like '/aa/bb/../cc' may cause converting links wrongly. This is a limitaion of the URI module's rel method. To cleanup pathes, Cwd::realpath is useful.
