一：maven：
<!--解析xml報文-->
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>
二：工具類：
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
/**
* @description 解析xml字符串
*/
public class Test {
public static void readStringXml(String xml) {
Document doc = null;
try {
doc = DocumentHelper.parseText(xml); // 將字符串轉爲XML
Element rootElt = doc.getRootElement(); // 獲取根節點
System.out.println("根節點：" + rootElt.getName()); // 拿到根節點的名稱
Iterator iter = rootElt.elementIterator("head"); // 獲取根節點下的子節點head
// 遍歷head節點
while (iter.hasNext()) {
Element recordEle = (Element) iter.next();
String title = recordEle.elementTextTrim("title"); // 拿到head節點下的子節點title值
System.out.println("title:" + title);
Iterator iters = recordEle.elementIterator("script"); // 獲取子節點head下的子節點script
// 遍歷Header節點下的Response節點
while (iters.hasNext()) {
Element itemEle = (Element) iters.next();
String username = itemEle.elementTextTrim("username"); // 拿到head下的子節點script下的字節點username的值
String password = itemEle.elementTextTrim("password");
System.out.println("username:" + username);
System.out.println("password:" + password);
}
}
Iterator iterss = rootElt.elementIterator("body"); ///獲取根節點下的子節點body
// 遍歷body節點
while (iterss.hasNext()) {
Element recordEless = (Element) iterss.next();
String result = recordEless.elementTextTrim("result"); // 拿到body節點下的子節點result值
System.out.println("result:" + result);
Iterator itersElIterator = recordEless.elementIterator("form"); // 獲取子節點body下的子節點form
// 遍歷Header節點下的Response節點
while (itersElIterator.hasNext()) {
Element itemEle = (Element) itersElIterator.next();
String banlce = itemEle.elementTextTrim("banlce"); // 拿到body下的子節點form下的字節點banlce的值
String subID = itemEle.elementTextTrim("subID");
System.out.println("banlce:" + banlce);
System.out.println("subID:" + subID);
}
}
} catch (DocumentException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
三：測試
public static void main(String[] args) {
String xmlString = "<html>"
+ "<head>"
+ " <title>dom4j解析一個例子</title>"
+ " <script>"
+ " <username>yangrong</username>"
+ " <password>123456</password>"
+ " </script>"
+ "</head>"
+ "<body>"
+ " <result>0</result>"
+ " <form>"
+ " <banlce>1000</banlce>"
+ " <subID>36242519880716</subID>"
+ " </form>"
+ " <form>"
+ " <banlce>200</banlce>"
+ " <subID>222222222222</subID>"
+ " </form>"
+ "</body>"
+ "</html>";
readStringXml(xmlString);
}
控制檯：
ps:更換xml的報文需要更改工具類的節點名稱
