Question

To make a backup copy of XML nodes, I must copy all the node elements to a new node. I have this code to do the copying.

foreach($xurll as $url)
{ 
  $urlid = $url->getAttribute('ID');
  $xurl = $dom->createElement("URL");
  $xurl->setAttribute("ID", $urlid);
  $xurlb->appendChild($xurl);

  $name = $url->getElementsByTagName ("NAME")->item(0)->NodeValue;
  $xuname     = $dom->createElement("NAME");
  $xunameText = $dom->createTextNode($name);
  $xuname->appendChild($xunameText);
  $xurl->appendChild($xuname);

  $urllink = $url->getElementsByTagName ("URLC")->item(0)->NodeValue;
  $xulink     = $dom->createElement("URLC");
  $xulinkText = $dom->createTextNode($urllink);  
  $xulink->appendChild($xulinkText); 
  $xurl->appendChild($xulink); 

}

This code retrieves the id for the URL node to be copied, but doesn’t retrieve the NAME or URLC.
What is the right way to get that information?

Answer 1

The NodeValue here should be lower case nodeValue, try this instead

  $name = $url->getElementsByTagName ("NAME")->item(0)->nodeValue
