NAME

parse_html - Parse HTML text

parse_htmlfile - Parse HTML text from file

SYNOPSIS

 use HTML::Parse;
 $h = parse_htmlfile("test.html");
 print $h->dump;
 $h = parse_html("<p>Some more <i>italic</i> text", $h);
 $h->delete;

 print parse_htmlfile("index.html")->as_HTML;  # tidy up markup in a file

DESCRIPTION

Disclaimer: This module is provided for backwards compatibility with earlier versions of this library. New code will probably prefer to use the HTML::Parser and HTML::TreeBuilder modules directly.

The HTML::Parse module provides functions to parse HTML documents. There are two functions exported by this module:

parse_html($html, [$obj])

This function is really just a synonym for $obj->parse($html) and $obj is assumed to be a subclass of HTML::Parser. Refer to HTML::Parser for more documentation.

The $obj will default to a internally created HTML::TreeBuilder object. This 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.

parse_htmlfile($file, [$obj])

Same as parse_html(), but obtains HTML text from the named file.

Returns undef if the file could not be opened, or $obj otherwise.

When a HTML::TreeBuilder object is created, the following variables control how parsing takes place:

$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.

$HTML::Parse::IGNORE_UNKNOWN

This variable contols whether unknow tags should be represented as elements in the parse tree. Default is true.

$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.

$HTML::Parse::WARN

Call warn() with an apropriate message for syntax errors. Default is false.
