lib::HTML::ParsUser Contributed Perl Documentalib::HTML::Parse(3)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 the HTML::Parser
manpage 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.
