Getting the attribute value of anchor tag in UL - mootools

Question

<div class="content">
<ul class="clean menu" id="topics">
<li class="drop png">
<div>
<span href="#" id="phone" style="BACKGROUND-POSITION: 13px -79px">Phone</span>
</div>
<ul class="clean menu sub">
<li>
<a cat="tech" class="sec_phone_0" href="javascript:void(0);" name="&lid=choose_category_phone_digital" rel="1">FiOS Digital Voice</a>
</li>
<li class="last">
<a cat="tech" class="sec_phone_1" href="javascript:void(0);" name="&lid=choose_category_phone_dialup" rel="1">Home Phone(Copper)</a>
</li>
<li class="last">
<a cat="tech" class="sec_phone_2" href="javascript:void(0);" name="&lid=choose_category_phone_fiosVoice" rel="1">FiOS Voice</a>
</li>
<li class="last" style="margin-bottom:7px;">
<a cat="tech" class="sec_phone_2" href="javascript:void();" name="&lid=choose_category_phone_wireless" rel="1">Verizon Wireless</a>
</li>
</ul>
</li>
</ul>
</div>
Now I need to select the "cat" value of Fios Voice. How can I do this in Mootools v1.3.2?
Need to set the value in cookie.

This script gets the property of link on click event.
window.addEvent('domready',function(){
$$('ul.sub')[0].getElements('a').each(function(el,ind){
el.addEvent('click',function(){
var cat = el.getProperty('cat');
alert(cat)
})
})
})
For case when <a cat="tech1" class="sec_phone_0 active" href="javascript:void(0);" name="&lid=choose_category_phone_digital" rel="1">FiOS Digital Voice</a> has class="active"
window.addEvent('domready',function(){
if($$('ul.sub')[0].getElements('a.active')[0]){
var cat = $$('ul.sub')[0].getElement('a.active').getProperty('cat');
alert(cat);
}
})
