Log: simplexml->query returns empty array if no nodes were found and false if libxml thinks the xpath-expression was invalid. Behaves now the same like DomXPath and fixes Bug #48601 Adjusted a test to reflect that change Bug: https://bugs.php.net/48601 (Re-Opened) xpath() returns FALSE for legitimate query Changed paths: U php/php-src/branches/PHP_5_4/ext/simplexml/simplexml.c U php/php-src/branches/PHP_5_4/ext/simplexml/tests/008.phpt U php/php-src/trunk/ext/simplexml/simplexml.c U php/php-src/trunk/ext/simplexml/tests/008.phpt Modified: php/php-src/branches/PHP_5_4/ext/simplexml/simplexml.c =================================================================== --- php/php-src/branches/PHP_5_4/ext/simplexml/simplexml.c 2011-08-31 11:27:36 UTC (rev 315882) +++ php/php-src/branches/PHP_5_4/ext/simplexml/simplexml.c 2011-08-31 11:44:22 UTC (rev 315883) @@ -1294,8 +1294,9 @@ result = retval->nodesetval; + array_init(return_value); + if (result != NULL) { - array_init(return_value); for (i = 0; i < result->nodeNr; ++i) { nodeptr = result->nodeTab[i]; if (nodeptr->type == XML_TEXT_NODE || nodeptr->type == XML_ELEMENT_NODE || nodeptr->type == XML_ATTRIBUTE_NODE) { @@ -1316,8 +1317,6 @@ add_next_index_zval(return_value, value); } } - } else { - RETVAL_FALSE; } xmlXPathFreeObject(retval); Modified: php/php-src/branches/PHP_5_4/ext/simplexml/tests/008.phpt =================================================================== --- php/php-src/branches/PHP_5_4/ext/simplexml/tests/008.phpt 2011-08-31 11:27:36 UTC (rev 315882) +++ php/php-src/branches/PHP_5_4/ext/simplexml/tests/008.phpt 2011-08-31 11:44:22 UTC (rev 315883) @@ -25,7 +25,10 @@ $sxe = simplexml_load_string($xml); var_dump($sxe->xpath("elem1/elem2/elem3/elem4")); +//valid expression var_dump($sxe->xpath("***")); +//invalid expression +var_dump($sxe->xpath("**")); ?> --EXPECTF-- array(1) { @@ -36,4 +39,10 @@ } } } +array(0) { +} + +Warning: SimpleXMLElement::xpath(): Invalid expression in %s on line %d + +Warning: SimpleXMLElement::xpath(): xmlXPathEval: evaluation failed in %s on line %d bool(false) Modified: php/php-src/trunk/ext/simplexml/simplexml.c =================================================================== --- php/php-src/trunk/ext/simplexml/simplexml.c 2011-08-31 11:27:36 UTC (rev 315882) +++ php/php-src/trunk/ext/simplexml/simplexml.c 2011-08-31 11:44:22 UTC (rev 315883) @@ -1294,8 +1294,9 @@ result = retval->nodesetval; + array_init(return_value); + if (result != NULL) { - array_init(return_value); for (i = 0; i < result->nodeNr; ++i) { nodeptr = result->nodeTab[i]; if (nodeptr->type == XML_TEXT_NODE || nodeptr->type == XML_ELEMENT_NODE || nodeptr->type == XML_ATTRIBUTE_NODE) { @@ -1316,8 +1317,6 @@ add_next_index_zval(return_value, value); } } - } else { - RETVAL_FALSE; } xmlXPathFreeObject(retval); Modified: php/php-src/trunk/ext/simplexml/tests/008.phpt =================================================================== --- php/php-src/trunk/ext/simplexml/tests/008.phpt 2011-08-31 11:27:36 UTC (rev 315882) +++ php/php-src/trunk/ext/simplexml/tests/008.phpt 2011-08-31 11:44:22 UTC (rev 315883) @@ -25,7 +25,10 @@ $sxe = simplexml_load_string($xml); var_dump($sxe->xpath("elem1/elem2/elem3/elem4")); +//valid expression var_dump($sxe->xpath("***")); +//invalid expression +var_dump($sxe->xpath("**")); ?> --EXPECTF-- array(1) { @@ -36,4 +39,10 @@ } } } +array(0) { +} + +Warning: SimpleXMLElement::xpath(): Invalid expression in %s on line %d + +Warning: SimpleXMLElement::xpath(): xmlXPathEval: evaluation failed in %s on line %d bool(false)
