DOMElement->setIdAttribute()

The second parameter doesn't exactly do, what you would expect. So use the method with care.



If it is TRUE the method works like a switch. 

If it is FALSE the method turns ID setting off.



A unit test demonstrates the exact behaviour:



    public function testSetIdAttribute() {



            $this->assertNull($this->dom->getElementById('testChild'));

            $this->child->setIdAttribute('id', TRUE);    



            $this->assertType('DOMElement', $this->dom->getElementById('testChild'));

            $this->assertNotNull($this->dom->getElementById('testChild'));



      // TRUE switches between on and off, while false turns it off. 

            $this->child->setIdAttribute('id', TRUE);    

            $this->assertNull($this->dom->getElementById('testChild'));

            $this->child->setIdAttribute('id', TRUE);    

            $this->assertNotNull($this->dom->getElementById('testChild'));

            $this->child->setIdAttribute('id', TRUE);    

            $this->assertNull($this->dom->getElementById('testChild'));

            $this->child->setIdAttribute('id', TRUE);    

            $this->assertNotNull($this->dom->getElementById('testChild'));



      // FALSE turns off and not on any more. 

            $this->child->setIdAttribute('id', FALSE);    

            $this->assertNull($this->dom->getElementById('testChild'));

            $this->child->setIdAttribute('id', FALSE);    

            $this->assertNull($this->dom->getElementById('testChild'));

            $this->child->setIdAttribute('id', FALSE);    

            $this->assertNull($this->dom->getElementById('testChild'));

    }
