Arquivo Discussoes de Programacao e Tecnologia 
Olá, estou com uma dúvida que não consigo resolver.
O problema é o seguinte, eu envio uma url como essa
http://xml.mercadolivre.com.br/jm/categsXml?as_site_id=MLB, e a mesma me retorna um XML.
Gostaria de saber como faço para ler esse XML para depois fazer o parsing dele. Existe alguma boa prática para isso, tanto para ler o xml quando para enviar a url.
Pelo visto, você tem um XML hierárquico, como se fosse um menu com submenus, que podem ter outros submenus. Poderíamos até usar DOM + XPath para facilitar, mas no seu caso talvez seja melhor usar apenas DOM e tomar cuidado com a hierarquia.

Recomendo o JColtrane
Dê uma olhada nas API’s :
URLConnection para recuperar o conteudo de uma url
JAXB para efetuar um parser em um XML
abraços
E ai mynameisflaw, beleza ?
Bom eu precisava fazer isso na web por acaso vc teria algum código pronto para fazer isso ? O problema não é o parsing, mas sim ler o response para pegar essa XML…
fala Mau blz e vc ?
olha se eh isso que voce precisa:
try {
StringBuilder xml = new StringBuilder();
URL url = new URL("http://www.guj.com.br");
URLConnection conn = url.openConnection();
BufferedReader br = new BufferedReader( new InputStreamReader( conn.getInputStream() ) );
String linha;
while ( ( linha = br.readLine() ) != null )
xml.append(linha);
br.close();
} catch (Exception ex) {
ex.printStackTrace();
}
O StringBuilder vai guardar todo o conteudo retornado.
abraços!
E mynameisflaw, beleza ?
Eu testei esse código e funcionou perfeitamente, porem vamos aos problemas.
1º) O XML é muito grande e por isso o processamento demora muito, tem como melhorar a performace ?
2º) Outra coisa, eu estou tentando usar o XStream e quando ele me retorna um StringBuilder eu dou um .toString(), nele, logo em seguida eu passou para um método do XStream chamado toXML(valor), que me retorna um String e assim dou um System.out.println(), porem no valor impresso, onde é para vim com < ou > ele me imprime caracteres como " e >. Isso é normal.
Abraços e obrigado pela ajuda.
