Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

<?php

/*please use the xml feed that I have provided as an example instead 
of the ebay.xml*/
$xml = simplexml_load_file('ebay.xml');

 $xml-
>registerXpathNamespace('ebay','urn:ebay:apis:eBLBaseComponents');

 $resp = $xml-
>xpath("//ebay:CurrentPrice[.=1.98]/parent::Item/Storefront/StoreName"
);
 
for($i=0;$i < count($resp)/2; $i++ )
{
	
foreach($resp[$i] as  $key => $value)
{
	//echo "['".$key."']=".$value."<br>";
	echo "[$key]= $value<br>";
	
}
}
?>

Actually instead of that whole "for and foreach" block we can use 
var_dump($rest);

and it will return bool(false).
