XML解析黑莓

Question

我想解析XML至極i got from this url

，我做解析這樣

connection = (HttpConnection)Connector.open(_url); 
//Build Documents Based on the File 
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
DocumentBuilder builder = factory.newDocumentBuilder(); 
builder.isValidating(); 
Document document = builder.parse(connection.openInputStream()); 
Element rootElement = document.getDocumentElement(); 
rootElement.normalize(); 
NodeList list = document.getElementsByTagName("current_conditions"); 
int check = list.getLength(); 
for(int i=0;i < check; i++){ 
    //NodeList children = list.item(i).getChildNodes(); 
    Node children = list.item(i).getFirstChild(); 
    String conditionData = new String(); 
    if (children.getNodeType()!= Node.TEXT_NODE){ 
     NamedNodeMap child = children.getAttributes(); 
     if(child.getNamedItem("data")!=null){ 
      conditionData = child.getNamedItem("data").getNodeValue(); 
      System.out.println("++++++++++++++++++++++++"+conditionData); 
     } 
    }   
} 

//displayNode(rootElement, 0); 

}catch (Exception e) { 
    // TODO: handle exception 
    System.err.println("++++++++++++++++++"+e.getMessage()); 
}

你list.item（Ⅰ）沒有孩子，所以孩子將是空的。無論如何，嘗試使用bb示例中的解析器。這裏是它的代碼：XMLDemo code
