PHP Bug Type: SimpleXML related
Bug description: SimpleXML converts empty nodes into object with nested array
Description:
------------
When I run the following script I get strange results that are difficult
to test against, and when converted to json, a real pain to use on the
client-side.
<?php
$xml = new
SimpleXMLElement('<foo><bar><![CDATA[]]></bar><baz/></foo>',
LIBXML_NOCDATA);
print_r($xml);
$json = json_encode($xml);
echo "{$json}\n";
?>
Since bar is empty (Even though it has a CDATA tag that is removed) before
it gets to me ... I should get something like this
bar => ""
OR
at most ...
bar => SimpleXMLElemebt object ()
but ... what I don't expect is this:
SimpleXMLElement Object
(
[bar] => SimpleXMLElement Object
(
[0] =>
)
...
When this data is converted to json ... I get bar:{"0":""} which requires
me to do typeof and other types of tests on the client-side.
I mentioned this issue to our resident FE PHP expert here at Y! and they
said to file a bug.
Reproduce code:
---------------
Run this script on the command line:
<?php
$xml = new
SimpleXMLElement('<foo><bar><![CDATA[]]></bar><baz/></foo>',
LIBXML_NOCDATA);
print_r($xml);
$json = json_encode($xml);
echo "{$json}\n";
?>
Expected result:
----------------
SimpleXMLElement Object
(
[bar] => ""
)
OR
SimpleXMLElement Object
(
[bar] => SimpleXMLElement Object
(
)
)
Actual result:
--------------
SimpleXMLElement Object
(
[bar] => SimpleXMLElement Object
(
[0] => ""
)
)
