html::parse(3)
NAME
HTML::Parse - Deprecated, a wrapper around HTML::Tree
Builder
SYNOPSIS
See the documentation for HTML::TreeBuilder
DESCRIPTION
Disclaimer: This module is provided only for backwards
compatibility with earlier versions of this library. New
code should not use this module, and should really use the
HTML::Parser and HTML::TreeBuilder modules directly,
instead.
The "HTML::Parse" module provides functions to parse HTML
documents. There are two functions exported by this mod
ule:
- 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 sub
class of "HTML::Parser". Refer to HTML::Parser for
more documentation. - If $obj is not specified, the $obj will default to an
internally created new "HTML::TreeBuilder" object con
figured 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 $obj.
- parse_htmlfile($file, [$obj])
- Same as parse_html(), but pulls the HTML to parse, from the named file.
- Returns "undef" if the file could not be opened, or
$obj otherwise. - When a "HTML::TreeBuilder" object is created, the follow
ing 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 struc
ture of the document. Default is false. - $HTML::Parse::WARN
- Call warn() with an apropriate message for syntax
errors. Default is false.
REMEMBER!
HTML::TreeBuilder objects should be explicitly destroyed
when you're finished with them. See HTML::TreeBuilder.
