An automatic regex learner?

I have strings with recurrent pattern. Like that:

/socket.io/1/xhr-polling/993bcoZK7UkiqsNYpbja?t=1407502307019
/socket.io/1/xhr-polling/993bcoZK7UkiqsNYpbja?t=2222222222222
/socket.io/1/xhr-polling/993bco56465456465465a?t=333333333333

And also thing like that:

/api/bucket/53e4ce6584df65130e7ead66/data/metadata
/api/bucket/465456456456465456445456/data/metadata
/api/bucket/898989898989898989898989/data/metadata

And much more like that.

How would be the best way to find patterns in these strings and to aggregate them ?

Like getting some sort of json:

{
   pattern : "/api/bucket/*/data/metadata"
   routes : ["/api/bucket/53e4ce6584df65130e7ead66/data/metadata",
             "/api/bucket/465456456456465456445456/data/metadata",
             "/api/bucket/898989898989898989898989/data/metadata"]
}
