</current>

我想获得这部分的价值。

**<temperature value="3.964" min="3.964" max="3.964" unit="celsius"/>**

Weather_temperature = parser.getAttributeValue(null, "value");

那是对的吗？

如果文档较小，则可以加载文档并使用xpath定位temperature节点并到达value属性：

XPath xpath = XPathFactory.newInstance().newXPath();
NodeList nodes = (NodeList) xpath.evaluate("/current/temperature", parser, XPathConstants.NODESET);
String temperatureValue = nodes.item(0).getAttribute("value");
