Оптимизация куска парсера

[Sh@man]

Помогите оптимизировать кусок кода, а то после рабочей недели ничего в голову не лезет. Спасибо.

this.cList = new XML();
this.cList = ListXML.firstChild;
this.media = this.cList.firstChild;
while (i<ListXML.firstChild.childNodes.length) {
curnode = this.media.firstChild;
//trace("this.media="+this.media);
ident = this.media.attributes.id;
//trace("ident="+ident);
ctype = curnode.firstChild.nodeValue;
ccode = curnode.nextSibling.firstChild.nodeValue;
ico_projection = curnode.nextSibling.nextSibling.firstChild.nodeValue;
built = curnode.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;
light = curnode.nextSibling.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;
sectorcode = curnode.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;
X = curnode.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;
Y = curnode.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;
_location = curnode.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;
rs = curnode.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;
quant = curnode.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.nextSibling.firstChild.nodeValue;

....
this.media = this.media.nextSibling;
i++;
}
