Puedes SimpleXML o DOM y usar xpath para lograr mostrarlo.
Algo como
Código PHP:
Ver original<?php
$xml = <<<XML
<cws-status-resp ver="1.0">
<proxy-users count="1" login-failures="3">
<user name="7256-OUMM" display-name="Prueba" sessions="1">
<session host="1.1.2.2" id="127" count="1/1" active="true" profile="dish" client-id="Generic" protocol="Newcamd"
context="UserID [0] CaID [1816] Providers [3] [00 01 01, 00 01 06, 00 01 02] Anonymous [Yes]" connected="Sat,

flags="F" avg-ecm-interval="9"><service id="7780" cdata="1e64" name="nick "/>
</session>
</user>
</proxy-users>
</cws-status-resp>
XML;
$obj = new SimpleXMLElement($xml);
$name = $obj->xpath('//service/@name');
foreach($name as $k => $v){
echo $v->name;
}
