Previous Comments: ------------------------------------------------------------------------ [2008-10-16 00:09:39] steve at stevegoodwin dot net Description: ------------ If you json encode a simplexml object, any xml leaf nodes will lose their attributes The attached script has two small xml strings. One with attributes on the leaf node, one without. When you run the script, attribute values disappear for the second json string Reproduce code: --------------- <?php $xml_string1 = '<?xml version="1.0"?><ItemList><Item ID="456"><ExtraTag>ABC</ExtraTag></Item><Item ID="789"><ExtraTag>DEF</ExtraTag></Item></ItemList>'; $xml_string2 = '<?xml version="1.0"?><ItemList><Item ID="456">ABC</Item><Item ID="789">DEF</Item></ItemList>'; $xml_obj = simplexml_load_string($xml_string1); $json = json_encode($xml_obj); print "Input XML Document: " . htmlentities($xml_string1) . "<br/>attributes are present:<br/>$json<br/><br/>"; $xml_obj = simplexml_load_string($xml_string2); $json = json_encode($xml_obj); print "Input XML Document: " . htmlentities($xml_string2) . "<br/>attributes are <b>Not</b> present:<br/>$json<br/><br/>"; phpinfo(); ?> Expected result: ---------------- Input XML Document: <?xml version="1.0"?><ItemList><Item ID="456"><ExtraTag>ABC</ExtraTag></Item><Item ID="789"><ExtraTag>DEF</ExtraTag></Item></ItemList> attributes are present: {"Item":[{"@attributes":{"ID":"456"},"ExtraTag":"ABC"},{"@attributes" :{"ID":"789"},"ExtraTag":"DEF"}]} Input XML Document: <?xml version="1.0"?><ItemList><Item ID="456">ABC</Item><Item ID="789">DEF</Item></ItemList> attributes are Not present: {"Item":["ABC","DEF"]} Actual result: -------------- json string above labeled with "attributes are present:" is correctly json encoded. json string above labeled with "attributes are Not present:" is incorrectly json encoded. The json object does not have the attribute name or values ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46309&edit=1
