this should read:
Q: when is an array not an array?
A: when its simpleXML
(just a joke, sorry).
honestly: i think simple-xml looks pretty slick at first sight, but
totally brain-damaged (if not -dead) at second sight. but that
personal impression may just be by me, because i'm not bright enough
to get it properly.
in simple_xml all your nodes are objects, strings and arrays at the
same time. they just behave differently on the context they are used
in.
forget about {section}, it doesn't work on them, but {foreach} works
fine since Smarty-2.6.8.
example.
curl -O http://slashdot.org/slashdot.xml
to get an xml-file for testing:
<?xml version="1.0"?>
<backslash xmlns:backslash="http://slashdot.org/backslash.dtd">
<story>

.....
</backslash>
then in php:
$backslash = simplexml_load_file(BASEDIR . 'simplexml/slashdot.xml');
$this->assign('backslash', $backslash);
and in the template:
{foreach from=$backslash->story item=story}
{$story->title}
{$story->url}
{/foreach}
gives me:
AOL Open Sourcing Audio & Video Technology

Will Next-Gen Consoles Kill Off PC Gaming?
http://slashdot.org/article.pl?sid=05/06/03/1510223
....
if you want to access child-elements of a node use {$node->child},
if you want to access attributes of a node use {$node.attrname},
if you want to dump the contents of a node use {$node}
i don't think that smarty is *that* bad on simple_xml, but i must
admit i don't know anybody that uses this combo in production.
