A good exercise while learning programming, is to write a calculator. To do this, I created some kind of DSL in BNF and want to ask for your help to improve it. With this minilanguage you should be able to add, multiply and assign values and expressions to names (a.k.a. create variables and functions). Hava a look at the BNF first: <Pr...

Hi Guys, How come you can't use the Class's traversing methods with variable's to set the parameters For instance Using this array: array(0 => array('element' => 'img[src=images/more.gif]', 'attribute' => 'parent()->href')); this works: foreach($this->contents->find($target[$key]['element']) as $keyz => $found) { $this->store[$ke...
