XML::LibXML::NodeList::Iterator(3) Iteration Class for XML::LibXML XPath results


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 );


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.
