Do you know of any popular PHP template engines for php that have concept of current context node?

Question

This question is related to this one http://stackoverflow.com/questions/3940927/is-there-anything-like-dwoo-s-with-or-loop-in-smarty-3-or-earlier

Basically I want to have something like current node from XSLT templates.

In XSLT when I write something like:

<xsl:for-each select="catalog/cd">
<tr>
  <td><xsl:value-of select="title"/></td>
  <td><xsl:value-of select="artist"/></td>
</tr>
</xsl:for-each>

artist actually refers to catalog/cd[1]/artist (and of course [2],[3] ... and so on if there are more cd-s)

Current context in which field names are understood changes inside for-each block.

I very much like this functionality. Do you know any popular PHP template engine (other than Dwoo) that has this functionality?

UPDATE:

Tim Fountain suggested:

// smarty
{foreach from=$cds item=cd}
    <tr>
        <td>{$cd->title}</td>
        <td>{$cd->artist}</td>
    </tr>
{/foreach}

but I'd prefer something like:

// dwoo
{foreach from=$cds}
    <tr>
        <td>{$title}</td>
        <td>{$artist}</td>
    </tr>
{/foreach}

which will not work.

Think about nested loop (let's assume cd has multiple artists):

// smarty
{foreach from=$cds item=cd}
    <tr>
        <td>{$cd->title}</td>
        <td><ul>
        {foreach from=$cd->artist item=$ar}
           <li>{$ar}</li>
        {/foreach}
        </ul></td>
    </tr>
{/foreach}

when I'd prefer

// dwoo
{foreach from=$cds}
    <tr>
        <td>{$title}</td>
        <td><ul>
        {foreach from=$artist}
           <li>{$}</li>
        {/foreach}
        </ul></td>
    </tr>
{/foreach}

Also If I also have a collection of music on cassettes I can iterate over it with same code:

// dwoo
{foreach from=$mcs}
    <tr>
        <td>{$title}</td>
        <td><ul>
        {foreach from=$artist}
           <li>{$}</li>
        {/foreach}
        </ul></td>
    </tr>
{/foreach}

I don't know if I could use same name for loop variable over and over like here:

// smarty, buggy?
{foreach from=$mcs item=o}
    <tr>
        <td>{$o->title}</td>
        <td><ul>
        {foreach from=$o->artist item=o}
           <li>{$o}</li>
        {/foreach}
        </ul></td>
        <td>{$o->title}</td>
    </tr>
{/foreach}

But I suppose inner $o would have overwritten outer $o

Answer 1

PHP itself?

If I understand correctly you want this functionality

<?php foreach($catalog as $cd): ?>
    <tr>
        <td><?php echo $cd['title'] ?>
        <td><?php echo $cd['artist'] ?>
    </tr>
<?php endforeach ?>

You can have this on its own inside a template file and have your controller create the $catalog array and pass it to the template.

Answer 2

Is this not just like a normal foreach loop? So for example in Smarty the equivalent would be:

{foreach from=$cds item=cd}
    <tr>
        <td>{$cd->title}</td>
        <td>{$cd->artist}</td>
    </tr>
{/foreach}

but all the templating options, and PHP itself, can do this.
