NAME
parse_html - Parse HTML text
parse_htmlfile - Parse HTML text from file
SYNOPSIS
use HTML::Parse;
$h = parse_htmlfile("test.html");
print $h->dump;
$h = parse_html("<p>Some more <i>italic</i> text", $h);
$h->delete;
print parse_htmlfile("index.html")->as_HTML; # tidy up markup in a file
DESCRIPTION
Disclaimer: This module is provided for backwards compatibility with
earlier versions of this library. New code will probably prefer to
use the HTML::Parser and HTML::TreeBuilder modules directly.
The HTML::Parse module provides functions to parse HTML documents.
There are two functions exported by this module:
- parse_html($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
the HTML::Parser manpage for more documentation.
The $obj will default to a internally created HTML::TreeBuilder
object. This 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 obtains HTML text 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.
