Question

I fear that this is a really stupid question but I am really stuck after trying a load of combinations for the last 2 hours. I am trying to pull the NAME out of the XML file

My XML file:

<?xml version="1.0"?>
<userdata>
<name>John</name>
</userdata>

My php:

  $doc          =  new DOMDocument();
  $doc          -> load( "thefile.xml" );
  $thename       =  $doc -> getElementsByTagName( "name" );
$myname= $thename -> getElementsByTagName("name") -> item(0) -> nodeValue;

The Error:

Catchable fatal error: Object of class DOMElement could not be converted to string in phpreader.php

I have tried

$myname= $thename -> getElementsByTagName("name") -> item(0) ;
$myname= $doc     -> getElementsByTagName("name") -> item(0) -> nodeValue;
$myname= $doc     -> getElementsByTagName("name") -> item(0) ;

but all fail. Guess I have tried just about every combination except the correct one 🙁

Answer 1

You may want $myname = $thename->item(0)->nodeValue. $thename is already the NodeList of all of the nodes whose tag is “name” – you want the first item of these (->item(0)), and you want the value of the node (->nodeValue). $thename should be more appropriately named $names, and you’d see why $names->item(0)->nodeValue makes sense semantically.

This Works For Me^TM.
