html::formattext::withlinks
HTML::FormatText::WithLinks(3) User Contributed Perl Documentation HTML::FormatText::WithLinks(3) NAME
HTML::FormatText::WithLinks - HTML to text conversion with links as footnotes SYNOPSIS
use HTML::FormatText::WithLinks; my $f = HTML::FormatText::WithLinks->new(); my $html = qq( <html> <body> <p> Some html with a <a href="http://example.com/">link</a> </p> </body> </html> ); my $text = $f->parse($html); print $text; # results in something like Some html with a [1]link 1. http://example.com/ my $f2 = HTML::FormatText::WithLinks->new( before_link => '', after_link => ' [%l]', footnote => '' ); $text = $f2->parse($html); print $text; # results in something like Some html with a link [http://example.com/] my $f3 = HTML::FormatText::WithLinks->new( link_num_generator => sub { return "*" x (shift() + 1); }, footnote => '[%n] %l' ); $text = $f3->parse($html); print $text; # results in something like Some html with a [*]link [*] http://example.com/ DESCRIPTION
HTML::FormatText::WithLinks takes HTML and turns it into plain text but prints all the links in the HTML as footnotes. By default, it attempts to mimic the format of the lynx text based web browser's --dump option. METHODS
new my $f = HTML::FormatText::WithLinks->new( %options ); Returns a new instance. It accepts all the options of HTML::FormatText plus base a base option. This should be set to a URI which will be used to turn any relative URIs on the HTML to absolute ones. doc_overrides_base If a base element is found in the document and it has an href attribute then setting doc_overrides_base to true will cause the document's base to be used. This defaults to false. before_link (default: '[%n]') after_link (default: '') footnote (default: '[%n] %l') a string to print before a link (i.e. when the <a> is found), after link has ended (i.e. when then </a> is found) and when printing out footnotes. "%n" will be replaced by the link number, "%l" will be replaced by the link itself. If footnote is set to '', no footnotes will be printed. link_num_generator (default: sub { return shift() + 1 }) link_num_generator is a sub that returns the value to be printed for a given link number. The internal store starts numbering at 0. with_emphasis If set to 1 then italicised text will be surrounded by "/" and bolded text by "_". You can change these markers by using the "italic_marker" and "bold_marker" options. unique_links If set to 1 then will only generate 1 footnote per unique URI as oppose to the default behaviour which is to generate a footnote per URI. anchor_links If set to 0 then links pointing to local anchors will be skipped. The default behaviour is to include all links. skip_linked_urls If set to 1, then links where the text equals the href value will be skipped. The default behaviour is to include all links. parse my $text = $f->parse($html); Takes some HTML and returns it as text. Returns undef on error. Will also return undef if you don't pass it undef. Returns an empty string if passed an empty string. parse_file my $text = $f->parse_file($filename); Takes a filename and returns the contents of the file as plain text. Returns undef on error. error $f->error(); Returns the last error that occured. In practice this is likely to be either a warning that parse_file couldn't find the file or that HTML::TreeBuilder failed. CAVEATS
When passing HTML fragments the results may be a little unpredictable. I've tried to work round the most egregious of the issues but any unexpected results are welcome. Also note that if for some reason there is an a tag in the document that does not have an href attribute then it will be quietly ignored. If this is really a problem for anyone then let me know and I'll see if I can think of a sensible thing to do in this case. AUTHOR
