I have a string from a clearcase cleartool ls command. /main/parallel_branch_1/release_branch_1.0/dbg_for_python/CHECKEDOUT from /main/parallel_branch_1/release_branch_1.0/4 I want to write a regex that gives me the branch the file was checkedout on ,in this case - 'dbg_for_python' Also if there is a better way than using regex, please let me know. Thanks in advance, Don
