DOM解析

DOM解析

非官方，不在jdk中。
使用步驟：
    1）導入dom4j的核心包。 dom4j-1.6.1.jar
    2）編寫Dom4j讀取xml文件代碼

示例：

        }

Domj4讀取API： 
類型：

節點：
    Iterator  Element.nodeIterator();  //獲取當前標籤節點下的所有子節點

標籤：
     Element  Document.getRootElement();  //獲取xml文檔的根標籤     
     Element   ELement.element("標籤名") //指定名稱的第一個子標籤
     Iterator<Element> Element.elementIterator("標籤名");// 指定名稱的所有子標籤
     List<Element>   Element.elements(); //獲取所有子標籤

屬性：
    String   Element.attributeValue("屬性名") //獲取指定名稱的屬性值
    Attribute    Element.attribute("屬性名")；//獲取指定名稱的屬性對象 
            Attribute.getName()  //獲取屬性名稱
            Attibute.getValue()  //獲取屬性值
    List<Attribute>  Element.attributes();  //獲取所有屬性對象
    Iterator<Attribute>     Element.attibuteIterator(); //獲取所有屬性對象
文本：
    Element.getText();  //獲取當前標籤的文本
    Element.elementText("標籤名") //獲取當前標籤的指定名稱的子標籤的文本內容

修改API

增加： 
        DocumentHelper.createDocument()  增加文檔
        addElement("名稱")  增加標籤
        addAttribute("名稱"，“值”)  增加屬性
修改：
        Attribute.setValue("值")  修改屬性值
        Element.addAtribute("同名的屬性名","值")  修改同名的屬性值
        Element.setText("內容")  修改文本內容
刪除
        Element.detach();  刪除標籤  
        Attribute.detach();  刪除屬性
