I originally developed this helper class to allow functions to be parsed in views, but in a fit of brilliance I realise it could also solve a lot of issues for people using languages in their views.
Please note this is completely untested, but may be beneficial to someone.
Please try it and modify it as needed, your interest could benefit the CI community.
Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

//if no translation is found use the variable as a literal
if (($line = $this->lang->line("$match[1]")) === FALSE) $line = $match[1];
$template = str_replace($match[0], $line, $template);

On a second look much of the code wasn't needed. Should work a bit faster now.
Please post your comments, Thanks for your interest as always.

Looks good
, the update will speed up the script.

It may be of use to pass in the language name to parse with and have the helper load that language file.
Code:
class Language
{
function parse($view, $data = array(), $lang = 'english')
{
$this->load->language($lang);
....EDIT
Update #1 = add language name to load

If i understand it correct you can code something like
Code:
// template.php
<h1>{pagetitle}</h1>
<?php foreach($blogitems as $item){ ?>
<div class="item">
<h2><?php echo $item['title']; ?></h2>
<p>{postedby} <?php echo $item['author']; ?></p>
<?php echo $item['content']; ?>
<?php } ?>
// controller
function blog()
{
$data['blogitems'] = $this->blog->last_entries();
return language::parse('template', $data);

[eluser]wiredesignz[/eluser]
Yes, except I used {?pagetitle}, but really after looking at your code, the ? is not even needed. Thanks xwero
Update #2 = remove ?
Of course the view can be echo'd or appended to $this->output as required

I find it strange you don't have to add files to the load->language method
Code:
function language($file = array(), $lang = '')
{
$CI =& get_instance();
if ( ! is_array($file))
{
$file = array($file);
}
foreach ($file as $langfile)
{
$CI->lang->load($langfile, $lang);
}

What is strange about it xwero? If $file is not an array it is converted to an array

As you can see the method makes use of the lang->load method which is the method that gets the language file which provides the line but because there is not file it should throw an error or you should have a /language/english/english.php file.
The language is the second parameter.
