( #3333=superdoc: print w/ replies, xml ) Need Help??

Hi, could someone give me pointers/pseudocode for converting a tab-delimited file into a different format?

My data looks like this:

Name_1 TT XL_927799.1 Name_1 PA PA_392 Name_1 AT ZX_003039195.1 Name_2 TT XL_931313.1 Name_2 AT ZX_003043016.1 Name_3 TT XL_929616.1 Name_3 PA PA_5040 Name_3 PA PA_6336 Name_4 TT XL_928294.1 Name_4 PA PA_917

And I want to get it into this format:

PA TT AT PA_392 XL_927799.1 ZX_003039195.1 XL_931313.1 ZX_003043016.1 PA_5040,PA_6336 XL_929616.1 PA_917 XL_928294.1

The information in each row is separated by tabs and any field containing more than one eg Name_3 has two PA entries, will produce both entries separated by a comma.

If there is no entry a blank should be left or I suppose "No corresponding entry"

Thanks
