Loop through xml nodes with simplexml - php

Question

Im trying to create a table of Jobs on my site, pulling info from an xml feed I have access to... I've looked at various examples online and videos but I can't seem to understand how it works. My xml feed returns the following node structure:
<OutputVacancyAsXml>
<Vacancy>
<VacancyID></VacancyID>
<Job></Job>
<ClosingDate></ClosingDate>
</Vacancy>
</OutputVacancyAsXml>
I've had success with pulling through one item with this code:
<?php
$x = simplexml_load_file('https://www.octopus-hr.co.uk/recruit/OutputVacancyAsXml.aspx?CompanyID=400-73A3BCA1-D952-4BA6-AADB-D8BF3B495DF6');
echo $x->Vacancy[5]->Job;
?>
But converting it to foreach seems to be where I'm struggling. Heres the code I have tried so far with no luck;
<?php
$html = "";
$url = "https://www.octopus-hr.co.uk/recruit/OutputVacancyAsXml.aspx?CompanyID=400-73A3BCA1-D952-4BA6-AADB-D8BF3B495DF6";
$xml = simplexml_load_file($url);
for ($i = 0; $i < 10; $i++) {
$title = $xml->OutputVacancyAsXml->Vacancy[$i]->job;
$html .= "<p>$title</p>";
}
echo $html;
?>
Thanks all :)

Answer 1

Taken from the documentation
Note:
Properties ($movies->movie in previous example) are not arrays. They
are iterable and accessible objects.
With that kept in mind you can simple run over the nodes with foreach
$xml = simplexml_load_file($url);
foreach ($xml->OutputVacancyAsXml->Vacancy as $vacanacy)
{
echo (string)$vacanacy->Job; // Echo out the Job Title
}

Ok looks like I found a solution. Heres the code that worked for me plus it contains a little bit of code that pulls out duplicated (it was displaying each item 4 times!)...
<?php
$x = simplexml_load_file('https://www.octopus-hr.co.uk/recruit/OutputVacancyAsXml.aspx?CompanyID=400-73A3BCA1-D952-4BA6-AADB-D8BF3B495DF6');
$num = count($x->Vacancy);
//echo "num is $num";
$stopduplicates = array();
for ($i = 0; $i < $num; $i++) {
$job = $x->Vacancy[$i]->Job;
$closingdate = $x->Vacancy[$i]->ClosingDate;
// http://stackoverflow.com/questions/416548/forcing-a-simplexml-object-to-a-string-regardless-of-context
$vacancyid = (string) $x->Vacancy[$i]->VacancyID;
if (!in_array($vacancyid, $stopduplicates)) {
echo '
<tr class="job-row">
<td class="job-cell">'.$job.'</td>
<td class="date-cell">'.$closingdate.'</td>
<td class="apply-cell">
Apply Here
</td>
</tr>';
}
$stopduplicates[] = $vacancyid;
} //print_r($stopduplicates);
?>
