Leitura de XML a partir de retorno de URL Google Maps

Programação Java
#1

Bom dia a todos.

Gostaria de uma sugestão para realizar a leitura de um arquivo xml que me é retornado a partir de uma URL de pesquisa do google Maps. O retorno é somente o endereço de acordo com a posição passada na url (Lat, Long).

URL: http://maps.google.com/maps/geo?output=xml&q=-22.738350,+-47.338135

[b]Pergunta: Gostaria de saber se é possivel realizar a leitura dos dados (Endereço, Bairro, Cidade, etc…) diretamente recebendo os valores em uma String ou precisarei receber este xml e coloca-lo em um arquivo TXT e depois realizar a leitura.

Resumindo: Consigo ler diretamente o xml sem precisar salvar o conteudo do mesmo localmente? Eu utilizaria DOM para o mesmo, mas diretamente no retorno da URL.[/b]

grato

Você pode pôr direto em uma string. Procure pelas classes InputSource e java.io.StringReader.

Mano vc consegui fazer isto?? Como?? Estou tentando desta maneira:

DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); domFactory.setNamespaceAware(true); DocumentBuilder builder = domFactory.newDocumentBuilder(); Document doc = builder.parse("http://maps.google.com.br/?q=de%2009910750%20para%2004686001&output=kml");

o problema eh q o meu obj “doc” esta vindo null… vc sabe oq poderia ser??

Abraco.
