聊天群成员记录统计
昨天大家在k群聊天，群主谈到清理长期潜水、不冒泡的成员，于是琢磨了一个成员聊天记录统计的小程序。
从kk聊天主面板下面的喇叭 ，打开“消息管理器”页面，选中要导出的群，导出时指定聊天信息保存文件的格式为txt；在聊天窗口左上角第一个图标，点击下拉后点击‘查看通讯录’。将成员全选后，复制到一个txt文档中。
以下是程序代码，仅是简单地实现了统计的功能，未考虑性能问题。

1 楼 _gougang 2013-04-10 不错，不错,学习了 2 楼 fw_lucifer 2013-04-10 比如一位的kk号是10000，另一位的是100001，会有问题吗？ 3 楼 zld406504302 2013-04-10 fw_lucifer 写道比如一位的kk号是10000，另一位的是100001，会有问题吗？

如果一个号码包含了另一个号码，肯定有问题的 4 楼 zld406504302 2013-04-10 zld406504302 写道fw_lucifer 写道比如一位的kk号是10000，另一位的是100001，会有问题吗？

逻辑中去掉了号码的“（）” 将“（）”携带着去match ，应该就没问题了。
没有考虑太周全，谢谢提示。
