Previous Comments: ------------------------------------------------------------------------ [2007-08-18 10:11:40] rrichards@php.net re-classifying as documentation issue. xpath() returns boolean on failure. ------------------------------------------------------------------------ [2007-08-17 13:39:17] jani@php.net Rob, you didn't get away that easy. :) ------------------------------------------------------------------------ [2007-08-15 14:27:41] cpriest at warpmail dot net According to the specs: > Always returns an array of SimpleXMLElement objects. While the xpath() is actually returning a boolean value. Here is some revised code which demonstrates an incorrect return value: <?php require_once('inc.backend.interactive.php'); header('Content-Type: text/plain'); set_time_limit(0); $ResponseBody = '<?xml version="1.0" encoding="UTF-8"?><postresponse><status accept="no">INVALID</status></postresponse>'; $objXML = new SimpleXMLElement($ResponseBody); $tMatches = $objXML->xpath('postresponse/status/@accept'); print_r($tMatches); print_r(gettype($tMatches)); // print_r((string)$tMatches[0]); ?> ------------------------------------------------------------------------ [2007-08-14 11:56:16] rrichards@php.net 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 output is correct. $objXML is document element ------------------------------------------------------------------------ [2007-08-14 01:12:55] cpriest at warpmail dot net Description: ------------ Non-absolute paths using ->xpath() do not match appropriately. With the given example, changing the xpath to '/postresponse/status/@accept' correctly returns "no" Reproduce code: --------------- <? $ResponseBody = '<?xml version="1.0" encoding="UTF-8"?><postresponse><status accept="no">INVALID</status></postresponse>'; $objXML = new SimpleXMLElement($ResponseBody); $tMatches = $objXML->xpath('postresponse/status/@accept'); print_r((string)$tMatches[0]); ?> Expected result: ---------------- "no" Actual result: -------------- xpath() returns no results ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42289&edit=1
