HTML::HeadParser - Parse section of a HTML document |
NAME
HTML::HeadParser - Parse <HEAD> section of a HTML document
SUPPORTED PLATFORMS
- Linux
- Solaris
- Windows
SYNOPSIS
require HTML::HeadParser; $p = HTML::HeadParser->new; $p->parse($text) and print "not finished";
$p->header('Title') # to access <title>....</title>
$p->header('Content-Base') # to access <base href="http://...";>
$p->header('Foo') # to access <meta http-equiv="Foo" content="...">
DESCRIPTION
The HTML::HeadParser is a specialized (and lightweight)
HTML::Parser that will only parse the <HEAD>...</HEAD>
section of an HTML document. The parse() method
will return a FALSE value as soon as some <BODY> element or body
text are found, and should not be called again after this.
The HTML::HeadParser keeps a reference to a header object, and the parser will update this header object as the various elements of the <HEAD> section of the HTML document are recognized. The following header fields are affected:
- Content-Base:
- The Content-Base header is initialized from the <base href=``...''> element.
- Title:
- The Title header is initialized from the <title>...</title> element.
- Isindex:
- The Isindex header will be added if there is a <isindex> element in the <head>. The header value is initialized from the prompt attribute if it is present. If not prompt attribute is given it will have '?' as the value.
- X-Meta-Foo:
-
All <meta> elements will initialize headers with the prefix
``
X-Meta-'' on the name. If the <meta> element contains ahttp-equivattribute, then it will be honored as the header name.
METHODS
The following methods (in addition to those provided by the superclass) are available:
- $hp = HTML::HeadParser->new( [$header] )
-
The object constructor. The optional $header argument should be a
reference to an object that implement the
header()andpush_header()methods as defined by the HTTP::Headers class. Normally it will be of some class that isa or delegates to the HTTP::Headers class.If no $header is given HTML::HeadParser will create an HTTP::Header object by itself (initially empty).
- $hp->parse( $text )
-
Parses some HTML text (see HTML::Parser->
parse())but will return FALSE as soon as parsing should end. - $hp->header;
- Returns a reference to the header object.
- $hp->header( $key )
-
Returns a header value. It is just a shorter way to write
$hp->header->header($key).
EXAMPLE
$h = HTTP::Headers->new; $p = HTML::HeadParser->new($h); $p->parse(<<EOT); <title>Stupid example</title> <base href="http://www.sn.no/libwww-perl/";> Normal text starts here. EOT undef $p; print $h->title; # should print "Stupid example"

The HTTP::Headers class is distributed as part of the libwww-perl package.
