Re: How do I use renderWith() outside a controller?

Your first function is correct. Add parent::onBeforePublish() in there.

function onBeforePublish(){
parent::onBeforePublish();
$xml = $this->renderWith('XML');
file_put_contents('/full/path/to/xml-file.xml', $xml);

}

It should be in the MyPage model. The only issue is 'XML' its looking for a template in the template dir called 'XML.ss'.

Perhaps make a new template call xmlexport.ss inside there you'll need to structure the nodes as you see fit. Then call renderWith('xmlexport')

Depending on what you're after you could just serialise the object to xml and write that out http://stackoverflow.com/questions/137021/php-object-as-xml-document
