Just a quickie that someone will probably be able to answer quickly...

I am parsing an XML doc, when the parser hits a null node, ie no date eg </nodata> my parser comes up with the a fatal error (Call to a member function on a non-object)

Here is a snippet of the parser, the last line causes the error.

foreach ($element->child_nodes() as $e) {
if (isset($e->tagname)) {
$element=$e->tagname;
$node=$e->first_child();
$data=htmlspecialchars($node->node_value());


I have tried various methods of trying to bypass the line depending on if the node_value is null, but nothing seems to work....I guess I must be missing something here as I am not that good with XML...

Sadly I am limited by the server and can only use PHP4 (so can't get version 5 XML goodies :-( !!!

Please, can anyone suggest anything?

Thanks.

As you don't have the try{} catch available, did you simply tried to check with an if() that the first_child() haven't returned a null value?
http://www.php.net/manual/en/functio...irst-child.php

(PHP >= 4.3 only) If no first child is found, NULL is returned.

PHP Code:

foreach ($element->child_nodes() as $e) {
  if (isset($e->tagname)) {
    $element=$e->tagname;
    $node=$e->first_child();
    if($node!==NULL){
      $data=htmlspecialchars($node->node_value());
    }
  }
} 


....cheers, I owe you a beer!!

I was using whether if (empty)...and that still caused a problem, but I've just used your suggestion Thierry and works just fine...I guess one of those things that when you are stuck you just can't see the simplest solution...

Muchas gracias amigo,

Glen

I'm up for the beer !
