前言
最近有个同事说一个xml解析，说是很复杂。然后让我给看看。我给解析完了。现在分享下，希望如果遇到同样问题的朋友随时可以借鉴参考。

解析思路
使用dom4j技术，以
>为标示符，进行分割，获取到想要获取数据的上一层，然后通过getElement获取一个元素或者getElements获取一组相同标签数据。
解析实战
1.第一步引入 dom4j
<dependency>
<groupId>org.dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>2.1.3</version>
</dependency>
2.引入我的xml解析工具类
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.XMLWriter;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.List;
/**
* Dom4j读取Element
*
* @author hfl
*/
public class XmlUtil {
private static Logger logger = LoggerFactory.getLogger(XmlUtil.class.getName());
public static List<Element> getElements(Document document, String path) {
return getElement(document, path).elements();
}
public static Element getElement(Document document, String path) {
String[] paths = path.split(">");
Element result = document.getRootElement();
for (String item : paths) {
try {
result = result.element(item);
} catch (Exception e) {
logger.error("get element error: ", e);
}
}
return result;
}
public static String getValue(Document document, String path) {
String[] paths = path.split(">");
Element result = document.getRootElement();
for (String item : paths) {
try {
result = result.element(item);
} catch (Exception e) {
logger.error("get element error: ", e);
}
}
return result.getText();
}
public static Document create() {
// 创建一个xml文档
Document doc = DocumentHelper.createDocument();
Element university = doc.addElement("university");
university.addAttribute("name", "tsu");
// 注释
university.addComment("这个是根节点");
Element college = university.addElement("college");
college.addAttribute("name", "cccccc");
college.setText("text");
return doc;
}
public static void write(Document doc) {
try {
File file = new File("src/dom4j-modify.xml");
if (file.exists()) {
file.delete();
}
file.createNewFile();
XMLWriter out = new XMLWriter(new FileWriter(file));
out.write(doc);
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
3.开始解析测试类
@Slf4j
public class DomTest {
@Test
public void xmlToList() throws Exception {
String path = "D:\\comp\\springboot2\\02\\vehicle-business\\vehicle-business-service\\src\\test\\java\\com\\wuzheng\\vehicle\\business\\domtest\\xmltest.xml";
Document dom = new SAXReader().read(new File(path));
List<Element> elist = XmlUtil.getElements(dom, "getOutptTplAsnResult>diffgram>NewDataSet");
for (Element element : elist) {
log.info("recordlist ----------------");
Map<String, String> map = element.elements().stream().collect(Collectors.toMap(Element::getName, Element::getTextTrim));
log.info("recordlist = {}", new Gson().toJson(map));
}
}
}
4.查看效果:
3条全部解析完毕!!!
大功告成！！
开通了个微信公众号：
搜索： 怒放de每一天
后续可能不定时推送相关文章，期待和大家一起成长！！
大功告成!!
