How to parse xml with e.target.name

I wanted to parse the xml file through e.target.name instead of using the switch function. The button are put into an Array and then in a for loop where I add to them te eventlistener.

Now it looks like this:

function samClick(e:MouseEvent):void
{
    switch (e.target)
    {
        case A0101 :
            p.p.arch_tekst.text = archTekst.archMen.A0101T;
            p.p.arch_opis.text = archTekst.archMen.A0101O;
        break;

        case A0102 :
            p.p.arch_tekst.text = archTekst.archMen.A0102T;
            p.p.arch_opis.text = archTekst.archMen.A0102O;
        break;

        case A0103 :
            p.p.arch_tekst.text = archTekst.archMen.A0103T;
            p.p.arch_opis.text = archTekst.archMen.A0103O;
        break;

        case A0104 :
            p.p.arch_tekst.text = archTekst.archMen.A0104T;
            p.p.arch_opis.text = archTekst.archMen.A0104O;
        break;
    }
}

but I wan't to make it work like this:

function samClick(e:MouseEvent):void
{
    p.p.arch_tekst.text = archTekst.archMen.(e.target.name + "T");
    p.p.arch_opis.text = archTekst.archMen.(e.target.name + "O");
}

but when I write the code in this way it's not working...

Can anyone help?
