NAME¶
HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder
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 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.
