HTML::Parse

NAME

VERSION

SYNOPSIS

  See the documentation for HTML::TreeBuilder

DESCRIPTION

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 unknown 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.
