From: web-php-bugs at sklar dot com Operating system: Linux PHP version: 5CVS-2004-01-22 (dev) PHP Bug Type: XML related Bug description: segfault and node text not displayed when returned from children() Description: ------------ When iterating through the results of the SimpleXML children() method, $element->name syntax returns the empty string instead of the text of the "name" tag. var_dump($element), however reports the correct value for the "name" property of $element. Reproduce code: --------------- $xml=' <drinks xmlns:hot="http://www.example.com/hot"> <hot:drink><hot:name>Coffee</hot:name></hot:drink> <hot:drink><hot:name>Tea</hot:name></hot:drink> <drink><name>Cola</name></drink> <drink><name>Juice</name></drink> </drinks>'; $sxe = simplexml_load_string($xml); foreach ($sxe as $element_name => $element) { print "$element_name is $element->name\n"; } foreach ($sxe->children('http://www.example.com/hot') as $element_name => $element) { print "$element_name is $element->name\n"; } Expected result: ---------------- drink is Cola drink is Juice drink is Coffee drink is Tea Actual result: -------------- drink is Cola drink is Juice drink is drink is Segmentation fault Substituting var_dump($element) for the print statement produces: object(simplexml_element)#5 (1) { ["name"]=> string(6) "Coffee" } object(simplexml_element)#4 (1) { ["name"]=> string(3) "Tea" } [New Thread 1076484640 (LWP 16144)] drink is Cola drink is Juice drink is drink is On the segfault, GDB reports: Program received signal SIGSEGV, Segmentation fault.
