dom4j读取xml文件-蒲公英云

dom4j读取xml文件

主要使用dom4j的SAXReader

1、pom引入dom4j

<dependency>
      <groupId>dom4j</groupId>
      <artifactId>dom4j</artifactId>
      <version>1.6.1</version>
    </dependency>

2、测试的xml文件

<?xml version="1.0" encoding="UTF-8"?>
<bookMarks>
    <bookMark>
        <name>Unix时间戳</name>
        <url>http://tools.sharejs.com/unixtime.html</url>
    </bookMark>
    <bookMark>
        <name>图片Base64编码</name>
        <url>http://www.bejson.com/ui/image2base64/</url>
    </bookMark>
</bookMarks>

3、读取xml内容的功能代码

public static Map<String, String> getElements(String file) throws DocumentException{
        List<Element> elements;
        Map<String,String> map = new HashMap<>();
        Document document = DocumentHelper.createDocument();
        SAXReader saxReader = new SAXReader();
        document = saxReader.read(new File(file));
        elements = document.getRootElement().elements();
        for(Element element:elements){
            map.put(element.elementText("name"), element.elementText("url"));
        }
        return map;
    }

4、测试代码

public static void main(String[] args){
        Map<String, String> bmarks = new HashMap<>();
        try {
            bmarks = MyXmlParser.getElements("bookmark.xml");
            for (Map.Entry<String, String> entry: bmarks.entrySet()) {
                System.out.println(entry.getKey() + " : " + entry.getValue());
            }
        } catch (DocumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
