How about:

foreach($xml->package->class as $class)
{
   echo $class->name . "<br />\n"; // just echo for now to see if it works
}

[wcboyd]

OK, I tried that and this is what I got:

Warning: Invalid argument supplied for foreach() in C:\exampxml.php on line 9

[NogDog]

OK, I'm guessing here, but maybe you can use xpath() something like this (it's difficult without knowing what the source XML actually looks like):

foreach($xml->xpath('/package/class/name/' as $name)
{
   echo $name . "<br />\n";
}

[wcboyd]

NogDog,

Thanks for all of your help so far...you have really gone above and beyond and I am VERY grateful.

I tried that but got the following error message:

Parse error: syntax error, unexpected T_AS in C:\exampxml.php on line 14

This is the line containing the foreach statement.

I have attached a small part of the XML file. The whole file is rather large. I had to rename it to .txt because the attach function did not like .xml

Thanks.

Craig

NogDog made a typo error. It should be:

foreach($xml->xpath('/package/class/name/') as $name)
{
   echo $name . "<br />\n";
}

[wcboyd]

Laserlight, thanks for helping me with the syntax, but now I get the following error:
Fatal error: Call to a member function xpath() on a non-object on line 3
which is the line with the "foreach" on it.

Thanks,

Craig

xpath() requires PHP 5.2.0 or later. Could that be the problem?

[wcboyd]

OK, I was using v5.1.2. Now I am using v5.2.3.

I think you guys know this already, but in case you don't I am calling the program from the command prompt in Windoze.

Here is the code I am using now:

foreach($xml->xpath('/package/class/name/') as $name) 
{ 
   echo $name . "<br />\n"; 
} 

And I am getting the following error msg:

Fatal error: Call to a member function xpath() on a non-object in C:\exampxml.php on line 4

I am not sure if this is an imporvement or not....:bemused:

[laserlight]

$xml has to be a SimpleXMLElement. What is it now?

[wcboyd]

Good catch again Laserlight. I had accidently commented out that line. Now, here is ALL of my code:

<?php

$xml = simplexml_load_file('c:\input.xml'); 
foreach($xml->xpath('/package/class/name/') as $name) 
{ 
   echo $name . "<br />\n"; 
} 


?>

Here are the errors I am getting:

Warning: SimpleXMLElement::xpath(): Invalid expression in C:\exampxml.php on line 4

Warning: SimpleXMLElement::xpath(): xmlXPathEval: evaluation failed in C:\exampxml.php on line 4

Warning: Invalid argument supplied for foreach() in C:\exampxml.php on line 4

Thanks.
