HTML::FormatText::WithLinks(3) User Contributed Perl Documentation HTML::FormatText::WithLinks(3)

       HTML::FormatText::WithLinks - HTML to text conversion with links as footnotes

	   use HTML::FormatText::WithLinks;

	   my $f = HTML::FormatText::WithLinks->new();

	   my $html = qq(
	       Some html with a <a href="http://example.com/">link</a>

	   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/

       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.

	   my $f = HTML::FormatText::WithLinks->new( %options );

       Returns a new instance. It accepts all the options of HTML::FormatText plus

	   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.

	   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

       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.

	   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.

	   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.

	   If set to 0 then links pointing to local anchors will be skipped.  The default
	   behaviour is to include all links.

	   If set to 1, then links where the text equals the href value will be skipped.  The
	   default behaviour is to include all links.

	   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.

	   my $text = $f->parse_file($filename);

       Takes a filename and returns the contents of the file as plain text.  Returns undef on


       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.

       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.

       Ian Malpass <ian@indecorous.com> was responsible for the custom formatting bits and the
       nudge to release the code.

       Simon Dassow <janus@errornet.de<gt> for the anchor_links option plus a few bugfixes and

       Kevin Ryde for the code for pulling the base out the document.

       Thomas Sibley <trs@bestpractical.com> patches for skipping links that are their urls and
       to change the delimiters for bold and italic text..
