SimpleXML emptiness

Currently, an empty check like the following returns false because SimpleXML only checks for node existence in has_property. I'd like to propose the attached patch to change this to look at the node's children and apply PHP's emptiness rules to the content. $data = '<?xml version="1.0 ?> <doc> <e1></e1> <e2>0</e2> <f1>foo</f1> <x eprop="" fprop="data" /> </doc>'; $s = simplexml_load_string($data); var_dump(empty($s->e1)); // Currently false var_dump(empty($s->e2)); // Currently false var_dump(empty($s->f1)); // False var_dump(empty($s->x['eprop'])); // Currently false var_dump(empty($s->x['fprop'])); // False Note that this patch only effects elements which only contains an empty text node or only a text node with a literal "0". If the element contains real children, then it's considered to be non-empty (even if those children are in turn empty themselves). -Sara
