How to seperate x, y axix values

I have a file named 'tree' which contains the x and y values in it. Its an old data so i couldnt remember some file name. So now i want to restore the x and y values separately. So how can i save the x,y values in a separate file.

Ex: tree = [1:2;3:4;8:9;21:22;34:35;9:10];

Now i want x values separate and y values separate. How can i do it?

Your description is not clear: do you already have a file with this data, or are the values stored in somehow else? Are you having problems reading the file data?

If you could upload the file then we could have a look at it and tell you how to read the data from it. Don't forget to push both buttons: Choose file and Attach file.
