使用PHP 5.0 轻松解析XML文档（4）

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

Array
(
    [name] =＞ 华联
    [address] =＞ 北京长安街－9999号
    [desc] =＞ 连锁超市
    [cat_food] =＞ Array
        (
            [attrs] =＞ Array
                (
                    [id] =＞ food
                )
            [goods_food11] =＞ Array
                (
                    [name] =＞ food11
                    [price] =＞ 12.90
                    [attrs] =＞ Array
                        (

                        (
                            [value] =＞ 好东西推荐
                            [attrs] =＞ Array
                                (
                                    [creator] =＞ hahawen

                    [price] =＞ 1290
                    [attrs] =＞ Array
                        (

                        )
                )
        )
    [cat_coat] =＞ Array
        (
            [attrs] =＞ Array
                (

                )
            [goods_coat31] =＞ Array
                (
                    [name] =＞ coat31
                    [price] =＞ 112
                    [attrs] =＞ Array
                        (
                            [id] =＞ coat31
                        )

                )
        )
    [special_hot] =＞ Array
        (

            [goods_0] =＞ Array
                (
                    [name] =＞ hot41
                    [price] =＞ 99
                )
        )
)

　　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
