一切都好。从互联网获取 xml，解析为 Document 但是当我试图从节点（）和一个节点之间获取一些值时（非常多云。）
private void parseWeather(Document srcDoc) throws Exception {
for (int a = 0; a < srcDoc.getElementsByTagName("record").getLength(); a++){
Node recordNode = srcDoc.getElementsByTagName("record").item(a);
Node temperatureNode = srcDoc.getElementsByTagName("temperature").item(a);
Node windNode = srcDoc.getElementsByTagName("wind").item(a);
Node bioNode = srcDoc.getElementsByTagName("bio").item(a);
RECORD = recordNode.getAttributes().getNamedItem("date").getNodeValue().toString();
TEMPERATURE = temperatureNode.getAttributes().getNamedItem("min").getNodeValue().toString();
WIND = windNode.getAttributes().getNamedItem("speed").getNodeValue().toString();
BIO = bioNode.getAttributes().getNamedItem("value").getNodeValue().toString();
Element element= (Element) srcDoc.getElementsByTagName("record").item(a);
NodeList status = element.getElementsByTagName("status");
NodeList text = element.getElementsByTagName("text");
Node statusNode = status.item(0);
Node textNode = text.item(0);
String statusText = statusNode.getFirstChild().getNodeValue();
String textText = textNode.getFirstChild().getNodeValue();
Log.e("Values", "STatus is " + statusText + " and text is " + textText);
}
}
这是xml文件

我得到了记录、温度、生物信息的输出，但没有状态和文本的输出。这个循环只会做一个。有谁能够帮我？
