Default vb4's each condition

in vb4 we can use <vb:each> as a foreach within templates. This is actually a very cool feature.

I am trying to port it to vb3 but am having some difficulty.

Looking into the files I have found 3 that correspond to this feature.
class_template_parser.php
adminfunctions_template.php
template_tag_defs.php

for creating vb3 if conditions the only file I could come up with that was responsible for them was.
adminfunctions_template.php

how could I go about adding this into vb3 so I could use for each's within templates?

The complete class is:
PHP Code:
class vB_TemplateParser_TagEach extends vB_TemplateParser_Tag
{
    public static function 
validate(vB_DomNode $main_nodevB_TemplateParser $parser)
    {
        
$errors = array();

        if (
strpos(implode('',$main_node->attributes),'(') !== false)
        {
            throw new 
vB_Exception_TemplateFatalError('template_text_not_safe');
        }

        if(!
parent::validateVar($main_node->attributes['from']))
        {
            
$errors[] = 'invalid_each_from';
        }

        if(!
parent::validateVar($main_node->attributes['value'], false))
        {
            
$errors[] = 'invalid_each_value';
        }

        if (isset(
$main_node->attributes['key']))
        {
            if(!
parent::validateVar($main_node->attributes['key'], false))
            {
                
$errors[] = 'invalid_each_key';
            }
        }

        return 
$errors;
    }

    public static function 
compile(vB_DomNode $main_nodevB_TemplateParser $parser)
    {
        
$key '';
        if (isset(
$main_node->attributes['key']))
        {
            
$key parent::compileVar($main_node->attributes['key']);
        }
        
$from parent::compileVar($main_node->attributes['from']);
        
$value parent::compileVar($main_node->attributes['value']);

        
$children $parser->_parse_nodes($main_node->childNodes());

        return 
"''" '; if (is_array(' $from ') || ' $from ' instanceof ArrayAccess) { foreach (' $from ' AS ' . ($key $key ' => ' '') . $value ') {' $parser->outputVar " .= '" $children "'; } }" $parser->outputVar " .= ''";  
    }
