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
xpath does not set the namespace scope of the returned
SimpleXMLelement.
You are required to set the namespace as demonstrated in previous
comment

If $child2 is <wsdl:operation/> then $child3 will be <wsdl:input/> or
<wsdl:output/> and there will be no $child4.
Unless this behaviour is considered as a bug by the developer and until
it is fixed, you'll have to specify the children's namespace when
calling children():
- $child2->children('http://schemas.xmlsoap.org/wsdl/') on PHP 5.1
and
later or
- $child2->children('wsdl', true) on PHP 5.2 and later

Description:
------------
SimpleXMLelement has no children() on element with only attributes?
I try to retreive an element by xpath which goes without problems, The
child elements it contains (same namespace) are all empty element with
only attributes. However the returned SimpleXML element does not contain
any children? so i'm unable to retreive there attributes.
Reproduce code:
---------------
<?php
$data = '<?xml version="1.0" encoding="utf-8"?>
<wsdl:definitions
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
targetNamespace="http://www.w3.org/2001/XMLSchema"
>
<wsdl:portType name="qxqPortType">
<wsdl:operation name="SOAP_set">
<wsdl:input message="SetRequest"/>
<wsdl:output message="SetResponse"/>
</wsdl:operation>
<wsdl:operation name="SOAP_get">
<wsdl:input message="GetRequest"/>
<wsdl:output message="GetResponse"/>
</wsdl:operation>
</wsdl:portType>
</wsdl:definitions>';
echo '<pre>';
$xml = simplexml_load_string($data);
if ($xml)
{
$res2 = $xml->xpath('//wsdl:portType/wsdl:operation');
//print_r($res);
foreach ($res2 as $child2)
{
//print_r($child2->children());
echo 'child2'.PHP_EOL;
print_r($child2->getName().PHP_EOL);
print_r(count($child2->children()).PHP_EOL);
print_r($child2);
foreach ($child2->children() as $child3)
{
echo 'child3'.PHP_EOL;
print_r($child3->getName().PHP_EOL);
print_r(count($child3->children()).PHP_EOL);
print_r($child3);
foreach ($child3->children() as $child4)
{
echo 'child4'.PHP_EOL;
print_r($child4->getName().PHP_EOL);
print_r(count($child4->children()).PHP_EOL);
print_r($child4);
}
}
}
}
echo '</pre>';
?>
Expected result:
----------------
child2 & child3 & child4 should be printed..
child2
operation
2
SimpleXMLElement Object
(
[@attributes] => Array
(
[name] => SOAP_set
)
)
child2
operation
2
SimpleXMLElement Object
(
[@attributes] => Array
(
[name] => SOAP_set
)
/* 2 another simplexml element input & output with children &
attributes*/
)
Actual result:
--------------
Only child2 prints with 0 children
child2
operation
0
SimpleXMLElement Object
(
[@attributes] => Array
(
[name] => SOAP_set
)
)
child2
operation
0
SimpleXMLElement Object
(
[@attributes] => Array
(
[name] => SOAP_get
)
)
