New Comment:
When I retrieve child elements like this:
foreach ($sxe->children('http://www.example.com/hot') as $element_name
=> $element) {
print "$element_name is
".$element->children('http://www.example.com/hot')."\n";
}
It works fine (duh). But I still get the segfault -- backtrace in my
previous comment.

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.
