Description:
------------
PEAR Package: XML_Tree-2.0.0RC2

Adding function getNodesAt($path) in XML_Tree_Node so you're able to get more nodes with same name.

Reproduce code:
---------------
/**
* Get references to nodes by its 'path'.
*
* @param mixed path Path to node. Can be either a string (slash-separated
* children names) or an array (sequence of children names) both
* starting from this node. The first name in sequence is a child name, not the name of this node.
*
* @return object Reference to the XML_Tree_Node found, or PEAR_Error if
* the path does not match any node.
* @access public
*/

function &getNodesAt($path)
{
if (is_string($path))
$path = explode("/", $path);

if (count($path) == 0) {
return $this;
}

$path1 = $path;
$next = array_shift($path1);

// Get all children of this node whose name is '$next'
$childs = array();

if (is_array($this->children) && (count($this->children) > 0)) {
for ($i = 0; $i < count($this->children); $i++) {
if (($this->children[$i]->name == $next) && (!is_null($this->children[$i]))) $childs[] =& $this->children[$i];
}
}

return $childs;
}

Expected result:
----------------
the return is an array with XML_Tree_Node objects in reference

Optimized a bit:

function &getNodesAt($path)
{
if (is_string($path)) $path = explode("/", $path);
if (count($path) == 0) return $this;

$path = array_shift($path);

// Get all children of this node whose name is '$next'
$childs = array();

if (is_array($this->children) && (count($this->children) > 0)) {
for ($i = 0; $i < count($this->children); $i++) {
if (($this->children[$i]->name == $path) && (!is_null($this->children[$i]))) $childs[] =& $this->children[$i];
}
}

return $childs;
}
