You might try searching for data recovery software and search for specific files or types of files, but if you reinstalled XP doing a fresh install that included a format on the same partition it is doubtful that you can recover any data from that partition without destroying the XP installation, and even then it is doubtful that any but the most specialized (and expensive) recovery software and someone very proficient at data recovery would be able to accomplish much.
There are services that specialize in data recovery. They are very costly and even then there is no guarantee of success because it depends on what you have overwritten and how many times it has been overwritten.
How much is the data worth to you?
