HTML::Parse − Deprecated, a wrapper around HTML::TreeBuilder
This document describes version 5.02 of HTML::Parse, released June 27, 2012 as part of HTML-Tree.
See the documentation for HTML::TreeBuilder
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.
HTML::TreeBuilder objects should be explicitly destroyed when you’re finished with them. See HTML::TreeBuilder.
