NAME

XmlMetaDataIterator - A Perl interface to the DbXml XmlMetaDataIterator Class

SYNOPSIS

     use Sleepycat::DbXml;
 
     my $manager = new XmlManager();
     my $doc = $mgr->createDocument();
     ...
 
     my $iterator = $doc->getMetaDataIterator();
 
     $manager->reset();
 
 
     my $xmlvalue = new XmlValue ;
     while ($iterator->next($uri, $name, $xmlvalue))
     {
     }
 
     my $scalar ;
     while ($iterator->next($uri, $name, $scalar))
     {
     }
 
 

DESCRIPTION

CONFORMANCE to C++ API

The Perl interface to XmlMetaDataIterator is identical to the C++ API.

Constructor

There is no constructor provided for this class. An XmlMetaDataIterator object is returned from the XmlDocument::getMetaDataIterator method.

Methods

$results->reset();

$results->reset();

$results->next($v); =head2 $results->next($scalar);

$results->next($v); =head2 $results->next($scalar);

Retrieves the next result from the result set and stores it in the $v parameter.

Returns true when another result is available, and false otherwise.

How the result is stored is dependant on the type of the $v parameter. If it is an XmlValue object the result will be stored directly in the object. Otherwise the contents of the $v parameter will be overwritten with a Perl string.
