当时在网上找了一个cdata的转换器， 修改之后， 将cdata标签给过滤掉。如下
复制代码 代码如下:
// states:
        //
        //     'out'
        //     '        //     '        //     '        //     '        //     '        //     '        //     '        //     'in'
        //     ']'

        //

        //
        $state = 'out';

        $new_xml = '';
        foreach ($a as $k => $v) {
            // deal with state.

最近发现，总是有alert发出来， 说是simplexml解析出错。
发现是原来有xml的数据是. 出现了连续的3个]， 造成上面的解析函数不能处理。
而且这个问题很难修正， 你不知道下次会不会有4， 5个]出现。
所以决定还是将这段解析 的代码换成dom xml，本身 dom的处理还是比较简单的，
包含domelement, domdocument, domnodelist, domnode几个 component.
对于 domnode有nodevalue, nodetype, nodename的成员函数。
首先先用loadxml将string转化为domdocument对像， 再用getelementsbytagname转化为domnodelist对像， 再使用->item(0)转化为domnode， 然后就可以使用上面的三种方法了。
对于 test这种xml标签， 要使用 attribute函数。
