下面是例子运行对结果:
下面是通过函数getSaveData()返回的整个xml数据的数组

下面是通过setValue()函数，给给根节点添加信息，添加后显示出结果xml文件的内容
＜?xml version="1.0" encoding="GB2312" ?＞

下面是通过getNode()函数，返回某一个分类下的所有商品的信息商品名：
food11Array
(
[name] =＞ food11
[price] =＞ 12.90
)
Array
(
[id] =＞ food11
)
商品名：food12Array
(
[name] =＞ food12
[price] =＞ 22.10
[desc] =＞ Array
(
[value] =＞ 好东西推荐
[attrs] =＞ Array
(
[creator] =＞ hahawen
)
)
)
Array
(
[id] =＞ food12
)
下面是通过findNodeByPath()函数，返回某一商品的信息商品名：
food11Array
(
[name] =＞ food11
[price] =＞ 12.90
)
Array
(
[id] =＞ food11
)
下面是通过setValue()函数，给商品"food11"添加属性, 然后显示添加后的结果
