NAME

XML::LibXML::NodeList::Iterator - Iteration Class for XML::LibXML XPath results

SYNOPSIS

   use XML::LibXML;
   use XML::LibXML::NodeList::Iterator;
 
   my $doc = XML::LibXML->new->parse_string( $somedata );
   my $nodelist = $doc->findnodes( $somexpathquery );
 
   my $iter= XML::LibXML::NodeList::Iterator->new( $nodelist );
 
   # more control on the flow
   while ( $iter->nextNode ) {
       # do something
   }
 
   # operate on the entire tree
   $iter->iterate( \&operate );

DESCRIPTION

XML::LibXML::NodeList::Iterator is very similar to XML::LibXML::Iterator, but it does not iterate on the tree structure but on a XML::LibXML::NodeList object. Because XML::LibXML::NodeList is basicly an array the functionality of XML::LibXML::NodeList::Iterator is more restircted to stepwise foreward and backward than XML::LibXML::Iterator is.
