array does not work after move to PHP5.4

Question

EDIT: I added my entire code om the bottom of this post My code below worked fine in PHP 5.3 but it is returning empty results in PHP 5.4 What is causing it?

This is the code I am using:

$xaxis=array();

    for ($i = 1; $i <= 3; $i++) {
        $chachg_time = $xml->xpath("//ns:BulkData[ns:Name='ChannelChangeHistory.{$i}.ChannelChangeTime']/ns:Value");
        $chachg_time = $chachg_time[0]; 
        $xaxis[] = $chachg_time[0];
     }

In PHP 5.3, I get the following result (which is what I am expecting):

Array
(
    [0] => SimpleXMLElement Object
        (
            [0] => 6
        )

)
Array
(
    [0] => SimpleXMLElement Object
        (
            [0] => 6
        )

    [1] => SimpleXMLElement Object
        (
            [0] => 5
        )

)
Array
(
    [0] => SimpleXMLElement Object
        (
            [0] => 6
        )

    [1] => SimpleXMLElement Object
        (
            [0] => 5
        )

    [2] => SimpleXMLElement Object
        (
            [0] => 3
        )

)

In PHP 5.4 I get the following:

Array
(
    [0] => SimpleXMLElement Object
        (
        )

)
Array
(
    [0] => SimpleXMLElement Object
        (
        )

    [1] => SimpleXMLElement Object
        (
        )

)
Array
(
    [0] => SimpleXMLElement Object
        (
        )

    [1] => SimpleXMLElement Object
        (
        )

    [2] => SimpleXMLElement Object
        (
        )

)

Here is the original workig code with php 5.3 Version

       while (false !== ($fname = readdir($handle)))  {            
         // Eliminate current directory, parent directory
         if (preg_match('/^\.{1,2}$/',$fname)) continue;            
         // Eliminate other pages not in pattern            
         if (! preg_match($pattern,$fname)) continue;
