XML is not parsed in php - php

Question

In my controller, I read a data from DB. (where AlarmDeatils is a stored as XML content. Eg:AlarmDeatils column contains
<SiteAlarmDetails>
<AlertId>89637</AlertId>
<SiteCode>20157498</SiteCode>
<SiteName>newport</SiteName>
<TankNumber>4</TankNumber>
<DispenserNumbedr>3</DispenserNumbedr>
<HoseNumber>3</HoseNumber>
<GradeId>11</GradeId>
<GradeName>PULP98</GradeName>
<AlarmUTCDateTime>2015-10-08T12:00:00</AlarmUTCDateTime>
<AlarmClearedUTCDateTime>2015-10-08T22:00:00</AlarmClearedUTCDateTime>
<UTCTimeZoneName>GMT Standard Time</UTCTimeZoneName>
<AlarmVolume>0</AlarmVolume>
<AlarmLevel>0</AlarmLevel>
<TankCapacity>0</TankCapacity>
<TankCapacityPercent>0</TankCapacityPercent>
<TankOverfill>0</TankOverfill>
<TankUllage>0</TankUllage>
<ProductLoss>0</ProductLoss>
<HoursElapsed>10</HoursElapsed>
<WaterLevel>0</WaterLevel>
<AvgSalesPerDay>0</AvgSalesPerDay>
<DaysToStockOut>0</DaysToStockOut>
<InvalidDataCount>0</InvalidDataCount>
<ValidDataCount>0</ValidDataCount>
<ZeroVolumeCount>0</ZeroVolumeCount>
<ZeroProductLevelCount>0</ZeroProductLevelCount>
<ZeroTotaliserAmountCount>0</ZeroTotaliserAmountCount>
</SiteAlarmDetails>
I read that that row in my controller like;
$tableAlarm = \DB::table('Alarm')
->where('Alarm.AlarmId', '=', $id)->first();
and when I use
var_dump($tableAlarm);
I get
object(stdClass)#241 (10) { ["AlarmId"]=> string(6) "245039" ["MessageNotificationId"]=> string(6) "219078" ["CompanyId"]=> string(2) "19" ["CompanyCode"]=> string(7) "MCCOLLS" ["AlertTypeId"]=> string(2) "23" ["AlarmDetails"]=> string(1408) "979381320106510Eyemouth Service Station2017-07-23T21:26:499999-12-31T23:59:59.9999999GMT Standard Time00000005000000000001-01-01T00:00:000001-01-01T00:00:000001-01-01T00:00:000000001-01-01T00:00:00" ["AlertProcessStateId"]=> string(1) "2" ["UTCDateTimeInserted"]=> string(27) "2017-07-24 02:15:36.9300000" ["UTCDateTimeUpdated"]=> string(27) "2017-07-24 02:15:36.9300000" ["RowDataVersion"]=> string(16) "00000000117D854B" }
Im trying to parse the AlarmDeatils column like;
$alertXml = simplexml_load_string( $tableAlarm->AlarmDetails);
echo $alertXml;//Nothing printed
But i'm not getting anything :( I'm trying to process that xml like;
foreach($alertXml->children() as $alerts)
{
print_r( $alerts->AlertId);// **getting SimpleXMLElement Object ()**
echo $alerts->AlertId;//**Nothing printed**
}

Hope this will be helpful. Try this simplest one.
Try this code snippet here
<?php
$xmlString=<<<XML
<SiteAlarmDetails>
<AlertId>89637</AlertId>
<SiteCode>20157498</SiteCode>
<SiteName>newport</SiteName>
<TankNumber>4</TankNumber>
<DispenserNumbedr>3</DispenserNumbedr>
<HoseNumber>3</HoseNumber>
<GradeId>11</GradeId>
<GradeName>PULP98</GradeName>
<AlarmUTCDateTime>2015-10-08T12:00:00</AlarmUTCDateTime>
<AlarmClearedUTCDateTime>2015-10-08T22:00:00</AlarmClearedUTCDateTime>
<UTCTimeZoneName>GMT Standard Time</UTCTimeZoneName>
<AlarmVolume>0</AlarmVolume>
<AlarmLevel>0</AlarmLevel>
<TankCapacity>0</TankCapacity>
<TankCapacityPercent>0</TankCapacityPercent>
<TankOverfill>0</TankOverfill>
<TankUllage>0</TankUllage>
<ProductLoss>0</ProductLoss>
<HoursElapsed>10</HoursElapsed>
<WaterLevel>0</WaterLevel>

<ValidDataCount>0</ValidDataCount>
<ZeroVolumeCount>0</ZeroVolumeCount>
<ZeroProductLevelCount>0</ZeroProductLevelCount>
<ZeroTotaliserAmountCount>0</ZeroTotaliserAmountCount>
</SiteAlarmDetails>
XML;
$xml=simplexml_load_string($xmlString);
echo (string)$xml->AlertId;//type-casted to string
echo PHP_EOL;
echo (string)$xml->SiteCode;
echo PHP_EOL;
echo (string)$xml->SiteName;
