一、测试用的XML文件

<?xml version="1.0" encoding="UTF-8" ?>
<bookstore>
    <book id="1">
        <name>书1</name>
        <author>作者1</author>
        <price>￥998</price>
    </book>
    <book id="2">
        <name>书2</name>
        <author>作者2</author>
        <price>￥998</price>
    </book>
    <book id="3">
        <name>书3</name>
        <author>作者3</author>
        <price>￥998</price>
    </book>
</bookstore>

二、解析XML文件

public class DomDemo {
    public static void main(String[] args) {
        InputStream inputStream = DomDemo.class.getClassLoader().getResourceAsStream("test.xml");
        DocumentBuilderFactory dom = DocumentBuilderFactory.newInstance();
        try {
            DocumentBuilder domBuilder = dom.newDocumentBuilder();
            Document document = domBuilder.parse(inputStream);
            Element bookstore = document.getDocumentElement();
            System.out.println(bookstore.getTagName());
            NodeList bookList = bookstore.getElementsByTagName("book");
            for (int i = 0; i < bookList.getLength() ; i++) {
                Node book = bookList.item(i);
                NamedNodeMap bookAttributes = book.getAttributes();
                for (int j = 0; j < bookAttributes.getLength(); j++) {
                    Node node = bookAttributes.item(j);
                    if (node.getNodeType() == Node.ATTRIBUTE_NODE){
                        System.out.println(node.getNodeName()+":"+node.getNodeValue());
                    }
                }
                NodeList bookChildList = book.getChildNodes();
                for (int j = 0; j < bookChildList.getLength(); j++) {
                    Node childItem = bookChildList.item(j);
                    if (childItem.getNodeType() == Node.ELEMENT_NODE){
                        System.out.println(childItem.getNodeName()+":"+childItem.getTextContent());
                    }
                }
                System.out.println("=======================");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

三、稍微有点麻烦了，建议使用Jsoup，操作更加方便

bookstore
id:1
name:书1
author:作者1
price:￥998
=======================
id:2
name:书2
author:作者2
price:￥998
=======================
id:3
name:书3
author:作者3
price:￥998
=======================
