You almost had it...
Since clothes is the root element you can think of your initial $xml as
<clothes>. So, you add a child to it. That error message is kinda cryptic
though.
<?php
$xml = <<<EOD
<?xml version="1.0" encoding="iso-8859-1"?>
<clothes>
<item>
<name>Red Gloves</name>
<desc>a pair of red gloves</desc>
<size>adult</size>
<price>12.99</price>
</item>
<item>
<name>Snow Boots</name>
<desc>some snow boots</desc>
<size>child</size>
<price>23.99</price>
</item>
</clothes>
EOD;
$sxml = simplexml_load_string($xml);
$item = $sxml->addChild('item');
$item->addChild('name', 'Blue Gloves');
echo $sxml->asXML();
exit;
