Você já leu algum tutorial sobre manipulação de XML com Java ? Mais especificamente, falando em DOM ?
Ai, é só trabalhar em cima do objeto. O que tu precisa extrair são atributos, então, torna-se tranquilo. Certo ?

Segue trecho de um codigo teste
[code] document = (Document) builder.build(xmlFile);
Element rootNode = document.getRootElement();
Element node = (Element) rootNode.getChild("RaceResults");
System.out.println("First Name : " + node.getChildText("PlayerName"));[/code]
Assim da certo de Imprimir a tag PlayerName. Mas se eu fizer assim
System.out.println("First Name : " + node.getChildText("Lap")); ai não vai.

Vamos lá. Primeiro passo e muito importante é conhecer a estrutura do seu XML. .
Vou postar o XML formatado, muito mais fácil de enxergar isso:
<?xml version="1.0" encoding="utf-8"?>

</rFactorXML> Vendo ele fica claro que o nó root é ‘rFactorXML’. Tudo abaixo desse nó é seu filho. Ele tem um filho apenas, chamado ‘RaceResults’, que por sua vez possui outros filhos, cujos filhos são netos de ‘rFactorXML’. Então, pensando assim, vamos procurar onde está a tag ‘Lap’.
Analisando o XML, temos ‘Lap’ sendo filho de ‘Driver’. Ok, achamos uma referência. Agora, quem é o nó ‘Driver’. ‘Driver’ tem como pai ‘Practice1’ que por sua vez é filho de ‘RaceResults’. Opa, finalmente chegamos ao ‘RaceResults’. Então, temos algo assim:
rFactorXML --> RaceResults --> Practice1 --> Driver --> Lap
