This example demonstrates how to manage trees
        that are saved in an XML-file

it reads out the entire file upon calling the method
        'setup', then you can work on the tree in whichever way
        you want, just have a look at the examples
        there are different ways to achieve things,
        i will try to demonstrate (all of) them     
        
        NOTE: for referening the XML-Nodes currently everything has to 
        be lower case, 
            SimpleTemplate/preFilter
        should be                   
            simpletemplate/prefilter

require_once 'Tree/Tree.php';

// calling 'setupMemory' means to retreive a class, which works on trees,
    // that are temporarily stored in the memory, in an array
    // this means the entire tree is available at all time
    // consider the resource usage and it's not to suggested to work
    // on huge trees (upto 1000 elements it should be ok, depending on your environment and requirements)
    // using 'setupMemory'
    $tree = Tree::setupMemory('XML',          // use the XML class to read an xml file
                                'config.xml'    // the DSN
                             );

// methods 'add' 'remove' and so on are not implemented yet, you can only read the tree for now
    // and navigate inside of it

// call 'setup', to build the inner array, so we can work on the structure using the
    // given methods
    $tree->setup();

    $element = $tree->data[$id]['child']['next']['next']; // refer to the third child of 'SimpleTemplate/preFilter/register'
