Is it better to use pure DOM methods or string concatenation to create a very dynamic xml file?

Question

I basically have to query the database in order to capture all the active properties, and then grab the content under each property for sections such as placement / experience and based on this generate basically a sitemap.

I am wondering if I should use only DOM methods (can I make a hundred or so createElements, inside loops, appendChildetc.) or just do a giant string concatenation and confirm that then render it as xml?

DOM XML. , .

$xmlBlock = '<foo>';
$xmlBlock .= '<bar>'.htmlspecialchars('baz', ENT_NOQUOTES, 'utf-8', false).'</bar>';
$xmlBlock .= '</foo>';

$node = $dom->createElement('foo');
$node->appendChild($dom->createElement('bar', 'baz'));

I don't know anything about PHP, but Android XmlSerializer is a good minimum API model that you need to provide guaranteed -built XML without creating a DOM in memory as part of the process. The code used is not complicated and can be built and tested separately from any applications that use it.
