XML strings to echo PHP - php

Question

I have a sophisticated feed that I want to echo the values of the XML file to PHP table.
Below is a sample of the UK RailDataFeed (Aka Darwin).
<?xml version="1.0" encoding="UTF-8"?>
<Pport xmlns="http://www.thalesgroup.com/rtti/PushPort/v12" xmlns:ns3="http://www.thalesgroup.com/rtti/PushPort/Forecasts/v2" ts="2018-01-01T21:58:48.2213864Z" version="12.0">
<uR updateOrigin="Trust">
<TS>
<Location pta="21:59" ptd="21:59" tpl="ROBY" wta="21:59" wtd="21:59:30">
<arr at="21:59" src="TRUST" srcInst="Auto" />
<dep et="21:59" src="Darwin" />
<plat conf="true" platsrc="A">4</plat>
</Location>
<Location pta="22:06" ptd="22:06" tpl="PRESCOT" wta="22:05:30" wtd="22:06">
<arr et="22:06" src="Darwin" wet="22:05" />
<dep et="22:06" src="Darwin" />
<plat>1</plat>
</Location>
</TS>
</uR>
</Pport>
I have been trying and researching all day to try to get the echo working but without any luck, I have tried the following
Test (1)
$xml=simplexml_load_file("log.xml") or die("Error: Cannot create object");
echo $xml->Location[0]['tpl'] . "<br>";
echo $xml->Location[1]->arr['at'];
echo $xml->Location[2]->dep['et'];
echo $xml->Location[3]->plat;
Test (2)
$xml=simplexml_load_file("log.xml") or die("Error: Cannot create object");
foreach($xml->children() as $loc) {
echo $loc->Location['tpl'];
echo $loc->arr['at'];
echo $loc->plat;
echo "<br>";
}
Test (3)
$file = file_get_contents('log.xml');
echo $file;
Still without any progress, After achieving this, I want to add the values to a bootstrap table too.
If any Ideas please share with me.

Answer 1

You can access attribute values via the attributes() method. Also, note that values are cast to string when echoing.
$str = <<<EOF
<?xml version="1.0" encoding="UTF-8"?>
<Pport xmlns="http://www.thalesgroup.com/rtti/PushPort/v12" xmlns:ns3="http://www.thalesgroup.com/rtti/PushPort/Forecasts/v2" ts="2018-01-01T21:58:48.2213864Z" version="12.0">
<uR updateOrigin="Trust">
<TS>
<Location pta="21:59" ptd="21:59" tpl="ROBY" wta="21:59" wtd="21:59:30">
<arr at="21:59" src="TRUST" srcInst="Auto" />
<dep et="21:59" src="Darwin" />
<plat conf="true" platsrc="A">4</plat>
</Location>
<Location pta="22:06" ptd="22:06" tpl="PRESCOT" wta="22:05:30" wtd="22:06">
<arr at="22:06" src="Darwin" wet="22:05" />
<dep et="22:06" src="Darwin" />
<plat>1</plat>
</Location>
</TS>
</uR>
</Pport>
EOF;
$xml = simplexml_load_string($str);
$c = 0;
foreach($xml->uR->TS->Location as $loc) {
echo (++$c) . "\n";
echo (string)$loc->attributes()['tpl'] . "\n";
echo (string)$loc->arr->attributes()['at'] . "\n";
echo (string)$loc->dep->attributes()['et'] . "\n\n";
}

Answer 2

After #marekful reply.
code modified to
<?php
$str = file_get_contents('log.xml');
$xml = simplexml_load_string($str);
$c = 0;
foreach($xml->uR->TS->Location as $loc)
{
echo (++$c) . "\n";
echo (string)$loc->attributes()['tpl'] . "\n";
echo (string)$loc->arr->attributes()['at'] . "\n";
echo (string)$loc->dep->attributes()['et'] . "\n\n";
echo (string)$loc->plat . "\n\n\n";
}
?>
And it worked perfectly with the sample xml file, but after adding the original XML file, It has multiple header in the file itself as shown below:

Is there a way to:
Ignore the multiple headers to avoid errors.
Post the echo value to a Bootstrap table.
Cheers!
