//index.php 創(chuàng)建功能
復(fù)制代碼 代碼如下:

jb51.NET$index = $doc -> createElement('index');//新建節(jié)點
jb51.NET$url = $doc -> createAttribute('url');//新建屬性
$patch = $doc -> createTextNode($_htmlpatch);//新建TEXT值
$url -> appendChild($patch);//將$patch文本設(shè)為$url屬性的值

總結(jié)一下，創(chuàng)建跟添加主要用的就是create跟appendChild，create后邊跟Element就是創(chuàng)建節(jié)點，跟Attribute就是創(chuàng)建屬性，TextNode就是創(chuàng)建值，然后appendChild就是設(shè)置從屬關(guān)系，這么一看非常簡單。刪除與修改都是用先獲得節(jié)點列表getElementsByTagName然后foreach遍歷想要修改的節(jié)點.
