XMLElement: passing XMLElement Object as $value fails

[iwyg]

When creating an new instance of XMLElement and passing another XMLElement (instead of a string ) as $value I get this error (public generate):

strlen() expects parameter 1 to be string, object given
/Users/malcolm/Sites/symdev/symphony/lib/toolkit/class.xmlelement.php line 592

587             }
588         }
589
590         $numberOfchildren = $this->getNumberOfChildren();
591
592         if($numberOfchildren > 0 || strlen($this->_value) != 0 || !$this->_selfclosing){
593
594             $result .= '>';
595
596

I did a quick test in evaluating that $this->_value is a string before getting its strlen. This would remove the error but the child element never gets appended to its parent Element.
Can you confirm this?

Yes I can confirm this bug, the documentation incorrectly (or correctly because I'd expect XMLElement to work this way) states that it can accept the $value as either a string or an XMLElement object. It's not the case, as you've documented.

Thanks for reporting.

For a immediate solution you can use new XMLElement('your-node-name', $value->generate()); which will create a string.
