dom4j来解析xml,通过URL获取服务器端返回的字符串,java swing 实现的页面
1)使用dom4j来解析xml字符串内容
import org.dom4j.DocumentHelper;
String domString = getDomString();
Document document = DocumentHelper.parseText(domString);
List<Element> list = document.selectNodes("table/tr/td/div/div/span");
String str = list.get(0).getText().substring(3).trim();
2)通过URL获取服务器端返回的字符串
import cp.common.IOUtils;
private static String getDomString() throws IOException{
InputStream in = null;
try {
URL url = new URL("http://10.12.123.40/userinfo.aspx");
URLConnection uc = url.openConnection();
uc.connect();
in = (InputStream)url.getContent();
byte[] buff = new byte[in.available()];
in.read(buff, 0, in.available());
String str = new String(buff, "UTF-8");
str = str.substring(StringUtils.indexOf(str, "table") - 1);
str = str.replace("TOPLEVEL", "").replace(" ", "").replace("┆", "");
return str;
} finally {
IOUtils.closeQuietly(in);
}
}
3) java swing 实现的页面

getContentPane().add(mainPanel, "mainPanel");
