org.dom4j.io.SAXReader reader = new org.dom4j.io.SAXReader();
            doc = reader.read(new File("conf/you.cfg.xml"));
            Element root = doc.getRootElement();
            List dbs = root.elements();

            if (dbs.size() > 0) {
                Element elm = (Element) dbs.get(0);
                String name = elm.getName();
                initConnProp(elm);
            }

------解决方案--------------------

试试这个吧，只能截取带<data>节点中是小数的：
Java code
        String xml = "<Row><Data>0</Data><Data>10057</Data><Data>8602</Data>\n<Data>114.018909</Data>\n<Data>23.209072</Data>\n<Data>广东省惠州市的G324附近,新禾村附近</Data></Row>";
        Pattern pattern = Pattern.compile("<data>(\\d*\\.\\d*)</data>", Pattern.CASE_INSENSITIVE);
        Matcher matcher = pattern.matcher(xml);

        ArrayList<String> lst = new ArrayList<String>();
        while (matcher.find()) {
            lst.add(matcher.group(1));
        }
        System.out.println(lst);

------解决方案--------------------
循环结束后：
String s1 = lst.get(1);
String s2 = lst.get(2);
