From: jordan dot raub at dataxltd dot com
Operating system: linux
PHP version: 5.2.8
PHP Bug Type: SimpleXML related
Bug description: Extending SimplXMLElement (or Iterator) w/ __toString
Description:
------------
implicit call to __toString() for the extended class does not work
properly an empty value is returned (even without the try catch block
nothing is returned)
Reproduce code:
---------------
<?php
class XML extends SimpleXMLElement
{
public function __toString()
{
try
{
$xml = new DOMDocument('1.0', 'utf-8');
$xml->formatOutput = TRUE;
$xml->preserveWhiteSpace = FALSE;
$xml->loadXML($this->asXML());
$retval = $xml->saveXML();
}
catch(Exception $e)
{
$retval = '';
}
return $retval;
}
}
$xml = new XML('<foo><bar/></foo>');
echo '|' . $xml . "|\n";
echo '|' . (string) $xml . "|\n";
echo '|' . $xml->__toString() . "|\n";
Expected result:
----------------
|<?xml version="1.0"?>
<foo>
<bar/>
</foo>
|
|<?xml version="1.0"?>
<foo>
<bar/>
</foo>
|
|<?xml version="1.0"?>
<foo>
<bar/>
</foo>
|
Actual result:
--------------
||
||
|<?xml version="1.0"?>
<foo>
<bar/>
</foo>
