Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php SimpleXMLElement represents both elements and attributes Previous Comments: ------------------------------------------------------------------------ [2008-12-05 16:33:42] maras3000 at gmail dot com You're right, that's a typo :) You are also right about attributes not having attributes. But in this case value returned by xpath() should be either array of values or false or sth else, because if you are getting a SimpleXMLElement in which you have [...@attributes] which contain what you were looking for and not being able to access them via attributes() method is somewhat wrong IMO. ------------------------------------------------------------------------ [2008-12-05 16:08:53] phpwnd at gmail dot com I think there are two errors in this reproduce code. First, there's a typo in the innermost foreach, $atribute instead of $attribute. Secondly, that XPath expression selects attributes (which explains why attributes() returns NULL, as attributes cannot have attributes), whereas it should select nodes. This code works as expected: Reproduce code: --------------- $xml = simplexml_load_file('./test.xml'); foreach ($xml->xpath('//*...@attr]') as $node) { foreach($node->attributes() as $attribute => $value) echo $attribute . " = " . (string)$value . "\n"; } ------------------------------------------------------------------------ [2008-12-05 14:29:47] maras3000 at gmail dot com Description: ------------ When looking for list of values of a certain attribute in xml via xpath() method, the returned SimpleXMLElement object's attributes() method does not properly return array of attributes. Reproduce code: --------------- test.xml: <?xml version="1.0"?> <test> <sth attr="1" /> <sth attr="2" /> <sth attr="3" /> </test> index.php: <pre> <?php $xml = simplexml_load_file('./test.xml'); $result = $xml->xpath('//@attr'); foreach($result as $node) { var_dump($node); foreach($node->attributes() as $attribute => $value) echo $atribute . " = " . (string)$value . "\n"; echo "---\n"; } ?> </pre> Expected result: ---------------- object(SimpleXMLElement)#2 (1) { ["@attributes"]=> array(1) { ["attr"]=> string(1) "1" } } attr = 1 --- object(SimpleXMLElement)#3 (1) { ["@attributes"]=> array(1) { ["attr"]=> string(1) "2" } } attr = 2 --- object(SimpleXMLElement)#4 (1) { ["@attributes"]=> array(1) { ["attr"]=> string(1) "3" } } attr = 3 --- Actual result: -------------- object(SimpleXMLElement)#2 (1) { ["@attributes"]=> array(1) { ["attr"]=> string(1) "1" } } --- object(SimpleXMLElement)#3 (1) { ["@attributes"]=> array(1) { ["attr"]=> string(1) "2" } } --- object(SimpleXMLElement)#4 (1) { ["@attributes"]=> array(1) { ["attr"]=> string(1) "3" } } --- ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46764&edit=1
