xml tag with one attribute and one value

Hello ... and thank you so very much for assisting!

The core libraries > utilities > xml documentation seems to imply that I can return the value of a tag's text by using '@' as the key. See following, straight from the documentation:

===============================

<?php

$xmlArray = array(

    'project' => array(

        '@id' => 1,

        'name' => 'Name of project, as tag',

        '@' => 'Value of project'

    )

);

$xmlObject = Xml::fromArray($xmlArray);

$xmlString = $xmlObject->asXML();

The content of $xmlString will be:

<?php

<?xml version="1.0"?>

<project id="1">Value of project<name>Name of project, as tag</name></project>

===============================

This is definitely what I would like to do, but whenever I use '@' as a key, I get a major page full of errors.

I would like to return something like: <project id="1">Value of project</project> (with no child tags)

In fact, and this is probably a different issue, I would really like to return: 

<projects>

<project id="1">Value of project</project>

<project id="2">Value of project</project>

<project id="3">Value of project</project>

<project id="4">Value of project</project>

</projects>

Again, thank you!!!

Kevin
