Parse XML sequentially in PHP

I want to be able to iterate through a SimpleXMLElementObject using PHP. However, I want to be able to do it without knowing the tag names in advance – I want a general solution that can be used as a discovery mechanism for the object’s key names. I’ve tried a bunch of ‘foreach’ type solutions but can’t get it to work.

Example code:

$schema = new SimpleXMLElement("<activity></activity>");
$schema->addAttribute("default-currency","asdf");
$schema->addAttribute("last-updated-datetime","jkl;");
$schema->addChild('title', 'example title');

print_r($schema) gives:

SimpleXMLElement Object ( 
    [@attributes] => Array ( 
        [default-currency] => asdf 
        [last- updated-datetime] => jkl; 
        ) 
    [title] => example title 
) 

Thanks

use getName function of SimpleXMLElement it will give you tag name

http://www.php.net/manual/en/simplexmlelement.getname.php

example

$sxe = new SimpleXMLElement("xml file");

echo $sxe->getName() . "\n";

foreach ($sxe->children() as $child)
{
    echo $child->getName() . "\n";
}
