NAME

HTML::HeadParser - Parse <HEAD> section of a HTML document

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 a HTML document. The parse() and parse_file() methods will return a FALSE value as soon as a <BODY> element is found, and should not be called again after this.

The HTML::HeadParser constructor takes a HTTP::Headers object reference as argument. The parser will update this header object as the various head elements are recognized.

The following header fields are initialized from elements found in the <head> section of a HTML document:

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.

X-Meta-Foo
All <meta> elements will initialize headers with the prefix ``X-Meta-''. If the element contains a http-equiv attribute, then it will be honored as the header name.

EXAMPLES 

 $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"
