Help with xpath and reading an xml file.

[tiki]

I need a way to grab a certain nodes value and return it, heres an xml file and a class I have, but I get this error, anyone know why or know how to fix it?

 

Parse error: syntax error, unexpected T_OBJECT_OPERATOR in data.php on line 22 (Line 22 is the return of the getName())

 

<?php
require_once("config.php");

class Data {

    var $race;
    var $data;
    var $doc;

    // Load the races xml data
    function Data($race) {
        $this->race = $race;
        
        $this->doc = new DOMDocument;
        $this->doc->load(_LIB_.'/data/'. $this->race .'.xml');
        $this->data = new DOMXPATH($this->doc);
    }
    
    // Gets the name of the unit
    function getName($unit) {
        return $this->data->query('//'. $this->race .'/units/'. $unit .'/node[. = \'name\']')->item(0)->nodeValue; 
    }
}
?> 

 

<?xml version="1.0" encoding="iso-8859-1"?>
<human>

I have a script to read xml file

 

This will o\p in array try it
