如何实现xml中的数据合并

如图片所示:
图片说明

在同一个pdbid的情况下(如:pdbid="1A1R"), 因为第3行的 ID=AC ,和第11行的 ID=CA 反序, 那么如何将 反序的ID对中的proBnd(第5行)和rnaBnd(第15行)合并, 同时rnaBnd(第7行)和proBnd(第13行)合并. 合并方式为若同"-"的则为"-" . 若同"+"或者一个"-"一个"+"的则为"+" .
如何通过代码实现???? (语言不限,java,c 优先) 在线寻求您的帮助~

测试文件如下:

三步走
1，读取xML数据，放放变量中。
2，修改数据。
3，写回xML。

只能读取xml 解析内容 修改数据 再写回xml 没办法直接自动修改

重新审查后,是自己处理出现问题,已经自行解决了~谢谢同仁的参与
