Refer http://livedocs.adobe.com/flex/3/html/help.html?content=13_Working_with_XML_08.html

in your case:

var x:XML; //fill Xml with your data

var threadWorks:XML = x.product.(@catalog=="Thread Works");

EDIT: Warning: Don't forget the . between product and @catalog

function onXmlLoaded (e:Event):void 
{
    xml = XML(e.target.data);
    var xmlLength:Number  = xml.product.length();
    for(var i:uint = 0; i<xmlLength; i++)
    {
            dataContainer.push( {
            catalog : xml.product.@catalog,
            name :  xml..name,
            price : xml..price,
            path : xml..path
        });
    }
    for(i=0;i<dataContainer.length;i++)
    {
           if(dataContainer[i].catalog[0]== "your String"){
                 showName();
           }
    }
}

i want trace only "Thread Works" not all xml. Allwith children . – Rajkamal Sep 08 '11 at 06:43
`trace(dataContainer[0].catalog[0]);` set the array location. – Benny Sep 08 '11 at 06:46
i want add only "Thread Works" and children to Array – Rajkamal Sep 08 '11 at 06:52
`catalog : xml.product.@catalog[0],` If you don't need in the array why do u keep that element wit xml? – Benny Sep 08 '11 at 06:55
MyCustom component window will access throw array Collection , so, if i am send current selected list of catalog to Array collection means it show current list("Thread Work") of gallery – Rajkamal Sep 08 '11 at 07:04
