Example for searchPath() usage

// Let's say our XML configuration looks like this:

// <config>
//   <db>
//     <user>root</user>
//     <password>pass</user>
//     <host>localhost</host>
//   </db>
// </config>

$config = new Config();
$root =& $menuObj->parseConfig('db.xml''xml');

// Will return the password directive in db
$passObj =& $root->searchPath(array('config''db''password'));

More complex example with attributes for searchPath()

// Let's say our XML configuration looks like this:

// <menu>
//   <group id="company">
//     <page id="news"/>
//     <page id="jobs"/>
//   </group>
//   <group id="projects">
//     <page id="project1"/>
//     <page id="project2"/>
//   </group>
// </menu>

$menuObj = new Config();
$root =& $menuObj->parseConfig('menu.xml''xml');

// Will return the container in menu which 'id' is set to 'projects'
$section =& $root->searchPath(array('menu', array('group', array('id' => 'projects'))));

// To get a page we could also use
$page =& $root->searchPath(array('menu',
'group', array('id' => 'projects')), 
'page',  array('id' => 'project2'))));
