=head1 NAME
HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder
=head1 VERSION
This document describes version 5.07 of
HTML::Parse, released August 31, 2017
as part of L<HTML-Tree|HTML::Tree>.
=head1 SYNOPSIS
See the documentation for HTML::TreeBuilder
=head1 DESCRIPTION
Disclaimer: This module is provided only for backwards compatibility
with earlier versions of this library. New code should I<not> use
this module, and should really use the HTML::Parser and
HTML::TreeBuilder modules directly, instead.
The C<HTML::Parse> module provides functions to parse HTML documents.
There are two functions exported by this module:
=over 4
=item parse_html($html) or parse_html($html, $obj)
This function is really just a synonym for $obj->parse($html) and $obj
is assumed to be a subclass of C<HTML::Parser>. Refer to
L<HTML::Parser> for more documentation.
If $obj is not specified, the $obj will default to an internally
created new C<HTML::TreeBuilder> object configured with strict_comment()
turned on. That class implements a parser that builds (and is) a HTML
syntax tree with HTML::Element objects as nodes.
The return value from parse_html() is $obj.
=item parse_htmlfile($file, [$obj])
Same as parse_html(), but pulls the HTML to parse, from the named file.
Returns C<undef> if the file could not be opened, or $obj otherwise.
=back
When a C<HTML::TreeBuilder> object is created, the following variables
control how parsing takes place:
=over 4
=item $HTML::Parse::IMPLICIT_TAGS
Setting this variable to true will instruct the parser to try to
deduce implicit elements and implicit end tags. If this variable is
false you get a parse tree that just reflects the text as it stands.
Might be useful for quick & dirty parsing. Default is true.
Implicit elements have the implicit() attribute set.
=item $HTML::Parse::IGNORE_UNKNOWN
This variable contols whether unknown tags should be represented as
elements in the parse tree. Default is true.
=item $HTML::Parse::IGNORE_TEXT
Do not represent the text content of elements. This saves space if
all you want is to examine the structure of the document. Default is
false.
=item $HTML::Parse::WARN
Call warn() with an appropriate message for syntax errors. Default is
false.
=back
=head1 REMEMBER!
HTML::TreeBuilder objects should be explicitly destroyed when you're
finished with them. See L<HTML::TreeBuilder>.
