responseXML.getElementsByTagName("z:row")

Hello All,

I am trying to understand the code below. Especially, the following line
var b=a.responseXML.getElementsByTagName("z:row");

Also, for the following (aryInfo[0] = b[0].getAttribute("ows_OAC");), where is the attribute coming from?

We are using SharePoint 2007.
Any help/explanation would be appreciated.


Thanks!

var aryReturn = new Array();
	var a=SPLISTCOLLECTION.getListItems("ProductList ","",'<Query><Where><Eq><FieldRef Name="Product Abbreviations" /><Value Type="Text">'+bName+'</Value></Eq></Where></Query>',"",1,"");
	var b=a.responseXML.getElementsByTagName("z:row");
    var aryInfo = new Array();
    aryInfo[0] = b[0].getAttribute("ows_OAC");
    aryInfo[1] = '';
