Export is broken or contains empty fields (addChild does not escape & to &)

[mbo-s]

Currently the Exportview uses the addChild method and this breaks, if the text contains an ampersand &

e.g. in the title
https://github.com/cross-solution/YAWIK/blob/develop/module/Jobs/view/jobs/export/feed.xml.phtml#L70

here the title is empty
<job id="5b3fc10b0acec3e060f8f502">
<title/>

expected value <title>Manager Sales &amp; Customer Relations</title>

What works is

$job->addChild('title');
$job->title = $jobObject->getTitle();

yes, you're right. It makes a difference.

cbleek@xenon:~$ php -a
Interactive mode enabled
php > $xml = simplexml_load_string('<jobopening/>');
php > $xml->addChild('title','a & b');
PHP Warning:  SimpleXMLElement::addChild(): unterminated entity reference               b in php shell code on line 1
PHP Stack trace:

@TiSiE interessant. Scheint ein gewünschtes Feature zu sein. Wusstest du das?

Quick fix

replace all addChild('node', 'content') calls with $job->node = 'content'

Pragmatic fix

Extend SimpleXmlElement and make the addChild method behave like we want.

class MySimpleXmlElement extends \SimpleXmlElement
{
  public function addChild($node, $content = null, $escape = true)
  {
     if ($escape) {
       $this->$node = $content;
       return $this->$node;
     }

     return parent::addChild($node, $content);
  }
}

DRY and SOLID fix

Encapsulate the XML generation in a dedicated class. Maybe a job decorator similar to Jobs\Entity\Decorator\JsonLdProvider.
Or a filter to convert a job entity into a XML representation.

+1 DRY and SOLID fix

@sergey-galenko That's one for you, I suppose :)

[gastro24]

let's wait for @mbo-s opinion. They are the only ones currently using XML export.

@gastro24 I use the mentioned Quick Fix, so I do not need any change

[cbleek]

Then we should set this onhold.
