Main problem here, is that you should rely on the content being valid XML
all the time. Especially when the content originates from user input (e.g.
through a CMS), this is hard to accomplish.

One safe solution would be to strip <br> tags and append elements/text nodes
where appropriate:

function eval_text_node_with_br(&$doc, &$child, $text) {
$text = preg_replace('!<br[^/>]*/?>!i', "\n", $text);
$text_array = preg_split('/(\r\n|\r|\n)/', $text);

foreach ($text_array as $i => $line) {
$child->append_child($doc->create_text_node($line));
$child->append_child($doc->create_element('br'));
}
}

$doc = domxml_new_doc("1.0");
$child = $doc->create_element('root');
eval_text_node_with_br($doc, $child, 'hello<br> world<BR />5');
$doc->append_child($child);
print htmlentities($doc->dump_mem());
