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
$objis assumed to be a subclass of
"HTML::Parser". Refer to HTML::Parser for more documentation.
$objis not specified, the
$objwill default to an internally created new
"HTML::TreeBuilder"object configured with strict_comment() turned on. That class implements a parser that builds (and is) a HTML syntax tree with HTML::Element objects as nodes. The return value from parse_html() is
- parse_htmlfile($file, [$obj])
- Same as parse_html(), but pulls the HTML to parse, from the named file.
"undef"if the file could not be opened, or
"HTML::TreeBuilder"object is created, the following variables control how parsing takes place:
- :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.
- :Parse::IGNORE_UNKNOWN:This variable contols whether unknow tags should be represented as elements in the parse tree. Default is true.:
- :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.:
- :Parse::WARN:Call warn() with an appropriate message for syntax errors. Default is false.:
