NAME
HTML::HeadParser - Parse 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
.... $p->header('Content-Base') # to access
$p->header('Foo') # to access
DESCRIPTION
The "HTML::HeadParser" is a specialized (and lightweight)
"HTML::Parser" that will only parse the ... section of an HTML document. The parse() method will return a FALSE value as soon as some element or body text are found, and should not be called again after this.Note that the "HTML::HeadParser" might get confused if raw undecoded
UTF-8 is passed to the parse() method. Make sure the strings are
properly decoded before passing them on.The "HTML::HeadParser" keeps a reference to a header object, and the
parser will update this header object as the various elements of the section of the HTML document are recognized. The following header fields are affected:Content-Base:
The Content-Base header is initialized from the
element. Title: The Title header is initialized from the... element. Isindex: The Isindex header will be added if there is aelement in the . The header value is initialized from the prompt attribute if it is present. If no prompt attribute is given it will have '?' as the value. X-Meta-Foo:
All elements will initialize headers with the prefix""X-Meta-"" on the name. If the element contains a
"http-equiv" attribute, then it will be honored as the header name.
MMEETTHHOODDSS The following methods (in addition to those provided by the superclass) are available:$hp = HTML::HeadParser->new
$hp = HTML::HeadParser->new( $header )
The object constructor. The optional $header argument should be a
reference to an object that implement the header() and pushheader() 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->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)".

$p = HTML::HeadParser->new($h);

Stupid example Normal text starts here. EOT undef $p;
print $h->title; # should print "Stupid example"
