Java 比较二进制文件的文本表示法

我有两个执行两个程序的xml报告。此类报告包含一个部分，其中列出了执行的所有i/o操作以及每个操作的内容。其中一些是xml，另一些是二进制的，但是报告中包含的数据总是文本的，所以我有一些类似的东西：

我必须对这些段进行比较，以找到相似之处，即两个程序是否向文件系统写入/读取相似的内容。另外，由于有许多i/o操作（100个）和许多报告（10000个），我应该很快完成。我正在使用java

有什么建议吗

最后我使用了标准化的压缩距离。我还不知道这是否是处理我的数据的最佳方法…

如何定义“相似”内容？这是问题之一XD将每个字符/字符集与整个第二个文档进行比较：p这将是相当大的负担先生XDI将提取3个或更多字母的字符串，为两个文档编制索引，然后比较这些索引的相似性。
