Hello perlmonks,

I am attempting pattern match on lines like this:

"Klhl21    NM_001033352    chr4    +    152008890    152017677    152008942    152015628    4    152008890,152012299,152014306,152015334,    152009963,152012705,152014379,152017677,"

I don't know how to write regex with "=~ m/" with an unknown number of commas to get the second two integer groups into memory. There can be a lot of these integers and writing a regex manually is impractical. There must be a smarter way to match the last two integer groups. So far, what I have is:

if (/^(.*)\s+(.*)\s+chr(.*)\s+([+-])\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s
++(\d+)/) {#indexed by RefSeqID

[download]

this reads all data but the last two integer groups into %D.

How can I pattern match the last two integer groups, with unknown numbers of alternating "(\d+),(\d+),(\d+)"?

Thanks,
-DEC
