SimpleXMLElement->children
Note to tudor:
You can't override the constructor, but you can get around that with a simple static method:
<?php
class simpleXmlExtender extends SimpleXMLElement {
public static function _new($xml=NULL, $ns=NULL, $prefix=TRUE) {
// allows you to set certain option parameters to new default values,
// or automatically decide whether input data is a file or not
// optionally, you can save the object in an intermediate variable
// and peform other actions on/with it before returning it
return new simpleXmlExtender($xml, LIBXML_NOCDATA, file_exists($xml), $ns, $prefix);
}
}
$simpleXML = simpleXmlExtender::_new($xmldata);
?>
... it's a bit of a hack, but it works.

A note about the undocumented parameters:
$ns (string): namespace prefix or URI
$is_prefix (bool): TRUE if $ns is a prefix, FALSE if it's a URI; defaults to FALSE
E.g.:
<?php
$xml_string = '<xml xmlns:foo='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'>
<foo:bar>..................';
$a = new SimpleXMLElement($xml_string, NULL, FALSE, 'foo', TRUE);
$b = new SimpleXMLElement($xml_string, NULL, FALSE, 'uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882', FALSE);
?>
However, I don't know exactly what these parameters are used for. They don't seem to be of much help when dealing with namespaces :-?

This class is extendable, but it's too bad that its constructor cannot be overriden (PHP says it's a final method). Thus the class should be wrapped using the delegation principle rather that extended.
