Hello there, I'm trying to find and replace a string value in XML. I've the below code so far. 

  #!C:/Perl/bin/perl.exe -w 

  #use strict; 

  use XML::XPath;
  use Data::Dumper;
  use XML::XPath::XMLParser; 

  my $xp = XML::XPath->new(filename => "new.xml"); 
 
  my $nodeset = $xp->findnodes('/catalog/book/titles/title');
  my @n = ("value one", "value two");
  print $nodeset->size;
  
  my $i = 0;
  
  foreach my $node ($nodeset->get_nodelist) {
   
    print "\nGET: " . $xp->getNodeText($node) . "\n";
    print "\nSET: " . $xp->setNodeText('/catalog/book/titles/title['."
+$i+1".']', $n[$i]) . "\n";
   
    $i++;
  }
  
  open('FILE', '>output.xml');
  my $nodes = $xp->find('/');  
  foreach my $node ($nodes->get_nodelist) {
        print FILE XML::XPath::XMLParser::as_string($node);
  }
 
  close(FILE);

I need to pass each node value to the setNodeText method. The XPath I've currently sets two child nodes at a time.

For example, I'd like to retrieve Book 1 through 4 one at a time and set each node value to a different value. In my code, when I try to set Book 1, it sets Book 3 to the same value. Likewise, when I try to set Book 2, the value of Book 4 is overwritten. Is there a way that I could pass one node to the setNodeText() method?

I appreciate any input.

Thanks
