实现的功能和上篇一样，只是将XML文件中的内容封装到一个对象中去

contact.xml

<?xml version="1.0" encoding="GBK"?>
<contactList>
    <contact id="001">
		<name>张三</name>
		<age>20</age>
		<phone>1234567</phone>
		<email>1234</email>
		<qq>222</qq>
	</contact>
	<contact id="002">
		<name>lisi</name>
		<age>20</age>
		<phone>1234567</phone>
		<email>1234</email>
		<qq>222</qq>
	</contact>
	<abc>
	    
	</abc>
</contactList>

Contact.java

//对象

package gz.itcast.a_dom4j_read;

public class Contact {
	public String id;
	public String name;
	public String age;
	public String phone;
	public String email;
	public String qq;
	
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	public String getPhone() {
		return phone;
	}
	public void setPhone(String phone) {
		this.phone = phone;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public String getQq() {
		return qq;
	}
	public void setQq(String qq) {
		this.qq = qq;
	}
	@Override
	public String toString() {
		return "Contact [id=" + id + ",name=" + name + ",age=" + age
				+ ",phone=" + phone + ",email=" + email + ",qq=" + qq
				+ "]";
	}
	
}
