After that make a file named as "test.php" that contains below code:

<?php

$ssString = '<OTA_HotelAvailRQ Version="1.0"><POS><Source><UniqueId Id="20000704abcde:105ABCDE" /></Source></POS><AvailRequestSegments><AvailRequestSegment><StayDateRange End="2011-08-15" Start="2011-08-14" />
            <RoomStayCandidates><RoomStayCandidate Quantity="1"><GuestCounts><GuestCount AgeQualifyingCode="10" Count="1" /></GuestCounts></RoomStayCandidate></RoomStayCandidates>
            <HotelSearchCriteria><Criterion><HotelRef Destination="East London, South Africa" CityCode="" CountryCode="" HotelName="" MinHotelRating="1"/><SearchCurrency>EUR</SearchCurrency>
            <AdditionalInfo Value="1" /><Language>EN</Language></Criterion></HotelSearchCriteria></AvailRequestSegment></AvailRequestSegments></OTA_HotelAvailRQ>';

include 'xmlParser.class.php';

$oXmlParser = new xmlParser();
$asArray = $oXmlParser->xml2array($ssString);
$asArray1 = $oXmlParser->xml2array($ssString,'');
$asArray2 = $oXmlParser->xml2array($ssString,1,'');
echo "<pre>";
print_r($asArray);
exit;
?>

Try this if any inconvenience please inform me if i can help you more.

Here is three different kind array you got by changing parameters like below use whatever satisfy your demand.

$asArray = $oXmlParser->xml2array($ssString);

$asArray1 = $oXmlParser->xml2array($ssString,'');

$asArray2 = $oXmlParser->xml2array($ssString,1,'');
