Previous Comments: ------------------------------------------------------------------------ [2011-01-04 14:33:51] aharvey@php.net Automatic comment from SVN on behalf of aharvey Revision: http://svn.php.net/viewvc/?view=revision&amp;revision=307081 Log: Fix doc bug #53633 (SimpleXML incorrectly gives NULL for attributes() with XPath value expression). ------------------------------------------------------------------------ [2011-01-04 14:28:08] aharvey@php.net Actually changing the bug type, which got reset when I previewed. Sorry about the noise. ------------------------------------------------------------------------ [2011-01-04 14:27:46] aharvey@php.net Morphing into a documentation bug: this is intentional per a comment in the SimpleXML source (SimpleXMLElement instances representing attributes instead of tags deliberately return NULL when attributes() is called), but needs to be documented on the SimpleXMLElement::attributes() manual page. ------------------------------------------------------------------------ [2010-12-30 08:35:44] barry at 091labs dot com Description: ------------ Apologies but I'm not running the SVN version as I only have hosting access to PHP, but I've searched through the bugs and have found nothing. Using 5.3.0, sorry if this has already been fixed. When using an XPath expression "/test/@attr1" to select one attribute, attributes() returns NULL when it should return the single attribute Test script: --------------- <?php $xml = simplexml_load_string("<test attr1=\"a\" attr2=\"b\"></test>"); $result = $xml->xpath("/test"); var_dump ($result[0]); //Prints attributes, all fine var_dump ($result[0]->attributes()); //Works fine $result = $xml->xpath("/test/@attr1"); var_dump ($result[0]); //Prints attribute "attr1", all fine var_dump ($result[0]->attributes()); //Should print same as above but returns null ?> Expected result: ---------------- The last var_dump should have printed the same as the previous var_dump Actual result: -------------- The last var_dump printed null ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53633&edit=1
