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



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->next ) {
      # 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.
