NAME
HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder
VERSION
This document describes version 5.07 of HTML::Parse, released August 31, 2017 as part of HTML-Tree.
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 module:
- 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
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 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 $obj.
- parse_htmlfile($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 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 appropriate message for syntax errors. Default is false.
REMEMBER!
HTML::TreeBuilder objects should be explicitly destroyed when you're finished with them. See HTML::TreeBuilder.
