in reply to Using XML modules to remove XML elements

Do you have the structure you have shown in a larger document, with enclosing elements? If so it would be possible to use, say, XML::DOM to find all the ISSN nodes and if they match the requirement then you can delete the parents.

    The root element of the document is <bulk-load> the document is made up of the <journal> elements. The entire document is close to 3 MB. I am looking into XML::DOM, since I am unfamiliar with XML modules used in Perl. I appreciate your advice..thanks.

      IN that case you can do something like: 

      use XML::DOM;
                                                                      
+              
                                                                      
+              
my $xml = 'jj.xml';
my $parser = new XML::DOM::Parser;
my $doc = $parser->parsefile($xml);
                                                                      
+              
my $nodes = $doc->getElementsByTagName ("ISSN");
                                                                      
+              
foreach my $node (@{$nodes})
{
   if ( $node->getFirstChild()->toString() eq '1742-7061' )
   {
      my $parent = $node->getParentNode();
      $doc->getFirstChild()->removeChild($parent);
   }
                                                                      
+              
}
                                                                      
+              
print $doc->toString();

      Of course in your production code you will want to have all the ISSN numbers you want removed in a hash and do exists rather than the single comparison I have there.

        Great!!! Thanks a lot..XML::DOM definitely seems to be an easier alternative..
