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 ( [id] =＞ food11 ) ) [goods_food12] =＞ Array ( [name] =＞ food12 [price] =＞ 22.10 [desc] =＞ Array ( [value] =＞ 好东西推荐 [attrs] =＞ Array ( [creator] =＞ hahawen ) ) [attrs] =＞ Array ( [id] =＞ food12 ) ) ) [cat_1] =＞ Array ( [goods_tel21] =＞ Array ( [name] =＞ tel21 [price] =＞ 1290 [attrs] =＞ Array ( [id] =＞ tel21 ) ) ) [cat_coat] =＞ Array ( [attrs] =＞ Array ( [id] =＞ coat ) [goods_coat31] =＞ Array ( [name] =＞ coat31 [price] =＞ 112 [attrs] =＞ Array ( [id] =＞ coat31 ) ) [goods_coat32] =＞ Array ( [name] =＞ coat32 [price] =＞ 45 [attrs] =＞ Array ( [id] =＞ coat32 ) ) ) [special_hot] =＞ Array ( [attrs] =＞ Array ( [id] =＞ hot ) [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
