=head1 NAME

HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder

=head1 VERSION

This document describes version 5.06 of
HTML::Parse, released April 28, 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 unknow 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>.
